Velocity and Acceleration Problems - Anne Elizabeth Franck | Library

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

1

Draw a diagram showing the motion of the quarterback.

1

Calculate the average velocity for his first run forward.

1

Calculate the average velocity when he is pushed backward.

1

Calculate the average velocity when he breaks the tackle

1

Calculate his total average velocity

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 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?
