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.
A cheetah can accelerate from rest to a speed of 30.0 m/s in 7.00 s. What is its acceleration?
A football quarterback runs 15.0 m straight forward 2.50 s.
He is then hit and pushed 3.00 m straight backward in 1.75 s.
He breaks the tackle and runs straight forward another 21.0 m in 5.20 s.
Use the average velocity formula to answer the questions to the right
Draw a diagram showing the motion of the quarterback.
Calculate the average velocity for his first run forward.
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?
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?
Calculate the average velocity when he is pushed backward.
Calculate the average velocity when he breaks the tackle
Calculate his total average velocity
