A robot drops a camera off the rim of a 239 m height cliff on Mars, where the free- fall acceleration is -3.7 m/s2 .
Find the velocity with which the camera hits the ground.
Find the time required for it to hit the ground.
A tennis ball is thrown vertically upward with an initial velocity of 8 m/s.
What will the ball’s speed be when it returns to its starting point?
How long will the ball take to reach its starting point?

With an average acceleration of -1.2 m/S2, how long will it take a cyclist to bring a bicycle with an initial speed of 6.5 m/s to a complete stop?
A car traveling at 7.0 m/s accelerates uniformly at 2.5 m/s2 to reach a speed of 12.0 m/s. How long does it take for this acceleration to occur?
tennis ball.
on launch, v = 8
on return, v = -8
for the time, 8-9.8t = -8
now you try the others. Just use your basic equations of motion.

now you try the others. Just use your basic equations of motion.
for example:
v = initial v + a t
x = initial x + initial v * t + (1/2) a t^2
v = initial v + a t
x = initial x + initial v * t + (1/2) a t^2
