Homework Statement A 60 kg person rides in a 20 kg cart moving at 13 m/s at the bottom of a valley that is in the shape of an arc of a circle with a radius of 36 m. What is the apparent weight of the person as the cart passes the bottom of the valley? Homework Equations F=ma F=(V^2/r) *...

we need vertical velocity to be 0 to find maximum height after leaving the ramp. this means we would have to find t when velocity equals 0, but after we find t what should I do? is there another SUVAT equation that yields y position at a specific time?

v^2 = v0^2 + 2a(x − x0) x = x0 + v0t + ½at^2 v = v0 + at

A test rocket is launched, starting on the ground, from rest, by accelerating it along an incline with constant acceleration a. The incline has length L, and it rises at θ degrees above the horizontal. At the instant the rocket leaves the incline, its engines turn off and it is subject only...
