Consider a dragster that, when the light turns green, accelerates uniformly from rest and completes a 372 meter race in a time of 6.61 seconds.
a) During this period, what is the dragster's acceleration expressed as a multiple of the acceleration due to gravity, g?
b) If the dragster could continue with this average acceleration, what would its speed be, in miles per hour, after it has traveled a total distance of 1.6km1.6km, which is approximately one mile?
Consider the velocity vs. time graph of a person in an elevator shown in Suppose the elevator is initially at rest.It then accelerates for 3 seconds, maintains that velocity for 15 seconds, then decelerates for 5 seconds until it stops. Theacceleration for the entire trip is not constant so we cannot use the equations of motion from Motion Equations for ConstantAcceleration in One Dimension for the complete trip. (We could, however, use them in the three individual sections whereacceleration is a constant.) Sketch graphs of (a) position vs. time and (b) acceleration vs. time for this trip.
A car traveling at 60 ft/sec begins decelerating (time is zero here, as is position) at a constant 10 feet per second squared. How many feet does the car travel before coming to a complete stop? Yet another hint: is the acceleration positive or negative? Then, determine the velocity function by integrating the acceleration function, and solving for C (the fixed point will be the velocity of the car at t=0). Integrate the velocity function to determine the position function, and solve for C (the fixed point will be the position when t=0 - and I gave that info above). One more thing...to find how long it will take to stop (which you will need in order to determine how many feet it takes to stop) you will need to use the velocity function and solve for t when v(t)=0.

- Please answer the following question(s): 1. The speed of a boat in still water is vá. A river flows with a speed of v₁. The boat travels distance of 19 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the vand v₁. Hint: Velocity=displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "v" and "v": Do v" and "v, add or substract downstream to give the resultant downstream velocity?
