Kalil and Sophia were learning about space and space travel in school. They were designing models of transport systems to learn about motion and forces. Their first activity was to build a balloon rocket that would transport a load of washers from one end of a string to the other. They recorded the results of their first attempts in the table below. Diameter of Balloon (inches) Number of Washers Distance Traveled (meters) 1.5 SC071616_01_2 Which one question is best answered by the patterns in the data? A Will changing the mass affect the distance the rocket flies? B Will changing the force affect the distance the rocket flies? C Will changing the distance the rocket flies affect the mass of the rocket? D Will changing the distance the rocket flies affect the force of the rocket? 8 1.8 10 2 2 2.4 OOOO D ABC O

Field testing has revealed the following information:1) The tank moves from rest to a speed of 50 ??/ℎ? in 100 seconds.2) Using the breaking system, the tank is brought to a complete stop from a speed of 50 ??/ℎ? in 5 seconds.3) The maximum speed achievable by the tank is 90 km/hr.You are required to address all the questions below providing all calculations, graphs, and explanations asappropriate to back your answers. Hint: make sure you are using consistent unitsFirst: Motion of the tank:a) Find the average driving acceleration of the tank.b) Calculate the average breaking acceleration of the tank.c) For parts (a) and b above parts report your answers in US Customary Units so that the information could beshared with experts from the US.d) How long would it take the tank to travel a distance of 12 km. Assume constant acceleration equal to that calculated inpart (a) up to the maximum achievable speed of 90 km/hr after which the tank maintains its speed constant.e) For the motion…

Assume constant acceleration equal to that calculated inpart (a) up to the maximum achievable speed of 90 km/hr after which the tank maintains its speed constant.e) For the motion described in part (d) above, find the expressions for the acceleration, velocity and the position of thetank as a function of time. Draw x(t), v(t), and a(t) for the entire 12 km trip. Assume motion is one dimensional alongthe x-axis starting from rest at…

A crate is pushed across the floor with a force of 522 N. If the crate has a normal force of 758N, what is the value of mu? Do NOT include units Round to the hundredths place

Which statement is parallel to this characteristic of the Vernier caliper? * O Vernier caliper is more precise than the meterstick. O Vernier caliper will give measurements that are concrete. O Vernier caliper is more accurate than the meterstick. O Vernier caliper will give measurements that are close to each other.

The coefficient of friction, u, can be determined in an experiment by measuring the force F required to move a mass m. When F is measured and m is known, the coefficient of friction can be calculated by: H- F/(mg) -9.81 m/s). friction Results from measuring F in six tests are given in the table below. Determine the coefficient of friction in cach test, and the average from all tests. Test Mass m (kg) Force F(N) 2 4. 3 4. 2 10 20 50 12.5 23.5 30 61 117 294

1. A 125-pound person contains 57 kilograms of matter. a. What is their weight in newtons? Caution: always show your work; always include units, vector directions, and "-" signs. b. Is this weight the force that their scales push them, or the force that they push the scales with? C. Is the scale reading more/less/or the same (choose one), if the scale sits on an escalator moving upward at constant speed? Explain:

The given graph shows stopping distances for trucks at various speeds on dry roads and on wet roads. Use this information to solve, a. Use the statistical menu of your graphing utility and the quadratic regression program to obtain the quadratic function that models a truck’s stopping distance, f(x), in feet, on wet pavement traveling at x miles per hour. Round the x-coefficient and the constant term to one decimal place. b. Use the function from part (a) to determine speeds on wet pavement requiring stopping distances that exceed 446 feet.
