Carlon launched a toy rocket vertically up from ground level (y = 0 m), at time t = 0.0 s. The rocket engine provides constant upward acceleration of 12.3 m/s2 during the burn phase. At the instant of engine burnout the rocket has risen to 89 m. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The maximum height reached by the rocket is closest to:

13) A toy rocket is launched vertically from ground level (y 0 m), at timet- 0.0 s. The rocket engine provides constant upward acceleration during the burn phase. At the instant of engine burnout, the rocket has risen to 72 m and acquired a velocity of 40 m/s. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The maximum height reached by the rocket is closest to:...

A rocket is launched straight up from the ground with constant acceleration. When it reaches a height of 240m, a bolt falls off the side of the rocket. The bolt hits the ground 6.0s later. A) How fast was the bolt (or rocket) going when it broke loose from the rocket? B) What was the rocket's acceleration? C) What was the maximum height that the bolt reached? Thanks.

(8%) Problem 11: A student launches a small rocket which starts from rest at ground level. At a height of h- 1.85 km the rocket reaches a speed of ve 395 m/s. At that height the rocket runs out of fuel, so there is no longer any thrust propelling it. Take the positive direction to be upward in this problem.

At time t = 0, a projectile is launched from ground level. At t = 2.00 s, it is displaced d = 51 m horizontally and h 76 m vertically above the launch point, what are the (a) horizontal and (b) vertical components of the initial velocity of the projectile? (c) At the instant it reaches its maximum height above ground level, what is its horizontal displacement D from the launch point?

A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...

Student Activity 9 A 30 kg rocket toy lifts off vertically from the ground. After 3 minutes, its engine stops. The rocket has then a speed of 320 m/s and is at an altitude of 2600 m. a) What is the work done by the rocket engine? b) What is the average power of the rocket engine? (Actually, the mass of the rocket decreases as fuel is ejected, but we will proceed as if the mass remains constant.)

A rocket, initially at rest on the ground, accelerates straight upward with constant net acceleration, from time t=0 until, at which time the fuel is exhausted
A rocket, initially at rest on the ground, accelerates straight upward with constant net acceleration, from time t=0 until, at which time the fuel is exhausted. Neglect air resistance and assume that the rocket stays close enough to the ground that the acceleration due to gravity (after the rocket engine stops) is given by g. a) Find the maximum height, h, that the rocket reaches above the ground. b) Find the total time of flight, that the rocket is in...
