A model rocket blasts off and moves upward with an acceleration of 12 m/s^2 until it reaches a height of 28 m , at which point its engine shuts off and it continues its flight in free fall.What is the speed of the rocket just before it hits the ground?
A certain freely falling object requires 1.1 s to travel the last 28 m before it hits the ground. (a) What was the velocity of the object when it was 28 m above the ground?(b) From what height above the ground did it fall?

Just the answer for c please, a is 6.27m/s and b is 6.1 m/s P5 An iron sphere is thrown straight up from a height of 2 m with a velocity of 0.3 m/s. It falls back to ground and bounces. After the bounce, it momentarily comes to a stop at a height of 1.9 m, where it is caught (a) What is the speed of the ball when it first reaches the ground? (b) What is its speed when...
A parachutist with a camera descends in free fall at a speed of 10 m/s. The parachutist releases the camera at an altitude of 50 m. (a) How long does it take the camera to reach the ground? (b) What is the velocity of the camera just before it hits the ground?
Problem 2: I throw a ball, mass m-5.0kg, at an initial speed of 3.0m/s, at an initial height of 1.7m, but at an angle of 37' with respect to the horizontal. It lands on the ground, at a final height of zero. (a) What is the initial velocity? (This is a VECTOR. Define ti as the horizontal, and +j as the vertical.) (b) What is the time when the ball obtains its maximum height? (c) What is the maximum height...

A brick is dropped (zero initial speed) from the roof of a building. The brick strikes the ground in 2.10 s. You may ignore air resistance, so the brick is in free fall. a) How tall, in meters, is the building? (b) What is the magnitude of the brick's velocity just before it reaches the ground? m/s (e) Sketch ay t, vy t, and yt graphs for the motion of the brick. (Do this on paper, Your instructor may ask...
