Question

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

oobleck · Accepted Answer

a = dv/dt = 0i - 9.8j and is constant. v=0 when vi + at = 0 using that value of t, v = vi + at

Damon · Answer

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)
