a ball is trough with initial velocity ui=(10i+15j)m/s when it reaches the top of trajectary negelecting air resistance what is its velocity and acceleration
Answered by oobleck
a = dv/dt = 0i - 9.8j and is constant.
v=0 when vi + at = 0
using that value of t,
v = vi + at

Answered by Damon
when it reaches the top the x velocity is still 10 and the y velocity is 0
V = 10 i + 0 j

The acceleration is 0 i - 9.8 j forever (until it hits ground)

An astronaut on a strange planet can jump a maximum horizontal distance of 15m if his initial speed is 3m/s. What is free fall acceleration on the planet?
