The position of a particle is given by r(t) = (3.0 t2 ˆi+ 5.0 ˆj − 6.0 t ˆk) m. (a) What is its speed at t = 1 s and t = 3 s? (b) What are the average velocity and acceleration between t = 1 s and t = 2 s?
The velocity of an object moving along the x-axis is given in m/s by
v(t) = t2 − 6t + 8, where t is in s. If the object starts from x=1m at t=0s, answer the following questions.
(a) What is the acceleration of the object when t = 2 s?
(b) What is the position when t = 3 s?(c) Is the object speeding up or slowing down at t = 1 s?
An object moves in one dimensional motion with constant acceleration a = 4.5 m/s².
At time t = 0 s, the object is at xo = 2.9 m and has an initial velocity of vo = 4 m/s.
How far will the object move before it achieves a velocity of v = 7 m/s?
Your answer should be accurate to the nearest 0.1 m.
