A tennis ball is dropped from 1.43 m above theground. It rebounds to a height of 0.945 m.
With what velocity does it hit the ground?
The acceleration of gravity is 9.8 m/s
2. (Let
down be negative.)
Answer in units of m/s
(This I already know -5.29 but I just don't know how to continue and do the rest of the parts)

Part 2
With what velocity does it leave the ground?
Answer in units of m/s.

Part 3
If the tennis ball were in contact with the
ground for 0.00638 s, find the acceleration
given to the tennis ball by the ground.
Answer in units of m/s
2.

Answers

Answer:

Part 2: 4.30 m/s

Part 3: 1503 m/s^2

Explanation:

First you already had -5.29 m/s

Part 2

With what velocity does it leave the ground ?

it is the same process as question 1, but in this case the height is 0.945 m

$v =√(2gh)$

$v =√(2*9.8*0.945) \nv =4.30\ m/s$

Part 3

This is a simple formula of :

$v_(f)-v_(i)=at \nwhere \nv_(f): final\ speed \nv_(i): initial\ speed \na: acceleration\nt: time$

Final speed: is the speed the ball leaves the ground = 4.30 m/s

Initial speed: is the speed the ball hits the ground = -5.29 m/s

4.30 - (-5.29) = 0.00638a

a = 1503 m/s^2

A road with a positive cross slope is highest __________.

Answers

A road with a positive cross slope is highest in the center of the road.

The roads with Cross slopes are formed to provide the drainage system so that water will run off from the surface. Due to this no water stands on the roads, especially when there is heavy rain it is very useful. It is a very important safety factor.
