Suppose a rocket launches with an acceleration of 35.0 m/s2 What is the apparent weight of...
If the astronaut throws the 3.20 kg tool with an acceleration of 7.50 m/s2 , what is the magnitude of the acceleration a of the astronaut during the throw? Assume that the total inertia of the astronaut is 88.0 kg .
A Rocket launches the summit of a mountain on some planet which has a constant acceleration of −3.5 m/s2 . If the projectile maximum height of 925.75 m above sea level at t = 7 seconds, how high is the mountain and when will the projectile reach sea level? Include correct units and be accurate to two decimal places
A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 80.2 m/s at ground level. The engines then fire, and the rocket accelerates upward at 4.10 m/s2 until it reaches an altitude of 1190 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of −9.80 m/s2. (You will need to consider the motion while the engine is operating and the free-fall motion separately.) (a)...

A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 79.0 m/s at ground level. The engines then fire, and the rocket accelerates upward at 4.20 m/s2 until it reaches an altitude of 930 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of -9.80 m/s2.

A 96.5-kg person stands on a scale in an elevator. What is the apparent weight when the elevator is (a) accelerating upward with an acceleration of 1.57 m/s2, (b) moving upward at a constant speed, and (c) accelerating downward with an acceleration of 1.79 m/s2?
A spaceship takes off vertically from rest with an acceleration of 27.5 m/s2.27.5 m/s2. What magnitude of force FF is exerted on a 54.0 kg54.0 kg astronaut during takeoff? Express FF as a multiple of the astronaut's weight ww on Earth.
An astronaut lifts off in a rocket from the surface of the moon, where g = 1.6 m/s^2. What vertical acceleration should his rocket have so that his apparent weight is equal to his true weight on earth?
A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 80.4 m/s at ground level. The engines then fire, and the rocket accelerates upward at 3.90 m/s2until it reaches an altitude of 1090 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of −9.80 m/s2.
