Use the formula for acceleration to solve the following problems.
Remember that Δv = vf - vo. Change in velocity is the final velocity minus the initial velocity.
Question 1
1.
A cheetah can accelerate from rest to a speed of 30.0 m/s in 7.00 s. What is its acceleration?
Question 2
2.
A motorcycle has a constant acceleration of 2.5 m/s2. Both the velocity and acceleration of the motorcycle point in the same direction. How much time is required for the motorcycle to change its speed from 21 to 31 m/s?
Question 3
3.
A runner accelerates to a velocity of 5.36 m/s due west in 3.00 s. His average acceleration is 0.640 m/s2, also directed due west. What was his velocity when he began accelerating?
