A helicopter is rising from rest vertially upward at 3 m/s2. At t=5 seconds, it launches a prjectile at 40 m/s at 30 degrees from the horizontal. a) depict a v/t graph of the helicopter from t=0 to t=5 b) calculate the height of the helicopter is above ground in 5 seconds. c) calculate the additional "vertical" height the projectile reaches after being launched from the helicoper. d) calculate how far horizontally the projectile would travel before striking the ground.

A rocket blasts off vertically from rest on the launch pad with a constant upward acceleration of 2.60 m/s2 .At 30.0 s after blastoff, the engines suddenly fail, and the rocket begins free fall. What is the height of the rocket when the engine fails? Find the magnitudes of the rocket's velocity and acceleration at its highest point. How long after it was launched will the rocket fall back to the launch pad?

A helicopter carrying Dr. Evil takes off with a constant upward acceleration of 7.0 m/s2 . Secret agent Austin Powers jumps on just as the helicopter lifts off the ground. After the two men struggle for 13.0 s , Powers shuts off the engine and steps out of the helicopter. Assume that the helicopter is in free fall after its engine is shut off, and ignore the effects of air resistance. Part A: What is the maximum height above ground...
