A projectile is launched from a point A at angle of 37˚ with an initial velocity of 10m/s up an incline plane that makes an angle of 8˚ with horizontal. The projectile hits the incline plane at a

point B. Calculate: a) the time it takes for the projectile to the incline plane. b) the distance AB.

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.
