## Homework Statement

Design projectile motion simulation and produce the max height, inital and final velocity, range, and time of flight. must use digital or photographic tech to record events and assist in the experiment>

Okay so ive designed a half projectile motion simulation. A ramp placed on at a height of 88cm. Ramps measurements being 49.5, 49.5 and 70 CM. A 45 degree angled ramp.

a ball is rolled down it at different heights to adjust the speed but just for understandings sake its being rolled at 70cm (max velocity for this exp)

using the video to time the balls flight from the the falling from the ramp and off the horiztonal piece thats been extended. The result is 0.434 seconds and the distance from the base of the falling point is 89 cm.

## Homework Equations

So from here i need to find the inital +final (same) velocities, the max height, and the angle needed to create this from the ground point.

Time (0.868s ?) and distance (1.78m ?) are already discovered by doubling recorded results (half projectile motion) and height is also established by the nature of the exp. (0.88m ?)

## The Attempt at a Solution

So for initial and final velocity

Ux = T x *change in X*

Ux = 0.434 x 0.89

Ux = 0.38626 ms -1

???

and to find the angle im pretty stumped.. i don't really know where to start from =|
