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:
A stomp rocket is launched vertically upwards with a burst of air, when a child jumps...
A stomp rocket is launched vertically upwards with a burst of air, when a child jumps on a flexible pillow connected to the launcher tube. Air resistance can be ignored in this question. At t=0, the rocket has just left the launcher, it has a speed of 25 m/s and the only force that it experiences is the force of gravity. "Up" is defined as the positive direction and define zero altitude as the position of the rocket at t=0....
A rocket blasts off vertically from rest on the launch pad with a constant upward acceleration...
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?

Need help in solving this problem a 2220-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=At+Bt2, where A and B are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 1.20 m/s2 and 1.80 s later an upward velocity of 1.64...

39. Rocket Motion Suppose a small single-stage rocket of total mass m) is launched vertically, the positive direction is upward, the air resistance is linear, and the rocket consumes its fuel at a constant rate. In Problem 22 of Exercises 1.3 you were asked to use Newton's second law of motion in the form given in (17) of that exercise set to show that a mathematical model for the velocity v(t) of the rocket is given...

Why
is the answer B?
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 1000 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 6600 m.You can ignore any effects of air resistance. What was the rocket's acceleration during the first 16 s? Express your answer with the appropriate units.

At time, t=0s, car A is at rest at the origin of the coordinate system and car B is moving due east at a constant velocity of 20.0m/s. When car B is 50.0m west of car A, car A starts to move at a constant acceleration of 2.00m/s2 due east. how far from the origin has car a moved when car B overtakes car A. use graph of position vs time for both cars.

A 2590-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=At+Bt2, where A and B are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 2.00 m/s2 and 1.60 s later an upward velocity of 2.46 m/s . At 4.30 s after...
