## Homework Statement

Hi, i have a small problem, can you guys help?

1.

A man jumps a maximum horizontal distance of 3 meters. How far can he jump on the moon, where downward acceleration is g/6?

#2

A 2 meter tall basketball player, 10 meters away from the hoop 3.05 meters high, launches a basketball at a 45 degree angle. What initial velocity must he use to get it in the hoop without touching the rim?

## Homework Equations

Vx= vintial*(cos theta)

X-displacement= Vx*T

V-y final= V-initial (sin theta) + AT

X displacement= V * T

## The Attempt at a Solution

For number one-

I split it in half- so now I'm trying to solve

A ball is rolled off the edge of a table and lands 1.5 meters away at 45 degrees. What is Vx,

Vy final, T, and height of the table?

So first, I use

Height= 1/2 g t^2

H= 4.9 *t^2

Since D= Vx * T,

Then T= D/vx

So H= 4.9 * D^2/vx^2

Tan 45= Vy/Vx,

Vx= Vy/tan45

D= 1.5 meters

So H= 4.9 * 2.25/ (vy/tan45)

tan45=1

H= 4.9* 2.25/vy^2

and this is where i stop.

For the second question, I was thinking of perhaps the changing it to

A ball is thrown from ground level, at a 45 degree angle, to a hoop 1.05 degrees.

After that, I have no clue

Thanks for answers!
