Question

1.A ball is thrown straight up with an initial speed of 12 m/s. What are the velocity and acceleration when it is at the top of its trajectory? Select all apply.

a=9.8m/s^2

v=12m/s

a= -9.8m/s^2

v=-12m/s

v=0

a=0

 

2. A ball is thrown straight up with an initial speed of 12 m/s. What are the velocity and acceleration when it is back to its original height?

a=9.8m/s^2

v=12m/s

a= -9.8m/s^2

v=-12m/s

v=0

a=0
