a model rocket is launched straight upward with an innitial speed of 11.0 m/s. it accelerates with a constant upward acceleration of 22 m/s^2 until its engines stop 3.0 seconds later. it then continues on as a free fall particle until it hits the ground.

(a) draw and label a diagram of the above and below information

(b) find the velocity (in m/s ) of the rocket at the instant it runs out if fuel.

(c)find the max height (in m) reached by the rocket

(d)how long (in seconds) is the rocket in the air

A model rocket is launched straight upward with an initial speed of 42.0 m/s. It accelerates with a constant upward acceleration of 2.50 m/s2 until its engines stop at an altitude of 160 m. (a) What can you say about the motion of the rocket after its engines stop?. (b) What is the maximum height reached by the rocket? (c) How long after liftoff does the rocket reach its maximum height? (d) How long is the rocket in the air?

1. A model rocket is launched straight upward with an initial space of 50.0 m/s. It accelerates with constant upward acceleration of 2.00 m/s^2 until its engines stop at an altitude of 150m. (a) how long does it take for the engines to stop? (b) what is the velocity of the rocket when its engine stop? (c) draw a graph for acceleration versus time (be careful to label your axis correctly). (d) what is the maximum height reached by the...

A fireworks rocket is launched vertically upward at 40 m/s. At the peak of its trajectory, it explodes into two equal-mass fragments. One reaches the ground t1 = 2.63s after the explosion. When does the second fragment reach the ground?

A 1246 kg weather rocket accelerates upward at 11.7 m/s2. It explodes 1.6 s after liftoff...

A 1246 kg weather rocket accelerates upward at 11.7 m/s2. It explodes 1.6 s after liftoff and breaks into two fragments, one twice as massive as the other. Photos reveal that the lighter fragment traveled straight up and reached a maximum height of 571 m. What were the speed of the heavier fragment just after the explosion?

An elevator accelerates upward at 1 m/s2. When the elevator is moving upward at 2 m/s,...

An elevator accelerates upward at 1 m/s2. When the elevator is moving upward at 2 m/s, a bolt drops from the ceiling which is 2.5 m above the ?oor. Assume that the bolt does not experience air resistance. Calculate how long it takes for the bolt to hit the ?oor, how far it travels, and how fast it is going when it hits the ?oor of the elevator. Solve this problem in two reference frames, one ?xed with respect to...

[10 pts] A model rocket is launched from a raised platform at a speed of 120 feet per second. Its height in feet is given by h(t) = -16t^2 +120 t + 32 where t represents seconds after launch. a. [3 pts] After how many second does the object reach its maximum height? Use the vertex formula. b. [2 pts] Use the previous result to find the maximum height reached by the rocket. c. [5 pts] After how many second...

A rocket is launched straight into the air with initial velocity 200 ft/s. Assume the launch is instantaneous. How high will it go, and how long will that take (use time increments of 0.01 seconds)? G= - 32.2 ft/s2 , H0=0 (the ground) V(t)=V0 + g t H(t)= H0 + V0 t + ½ g t2 The rocket deploys a parachute after 9 seconds and descends at a constant rate of 20 ft/sec. How long does it take to reach...

A rocket is fired straight upward, starting from rest with an acceleration of 25.0 m/s2. It runs out of fuel at the end of 4.00 s and continues to coast upward, reaching a maximum height before falling back to Earth. (a) Find the rocket’s height when it runs out of fuel; (b) find the rocket’s velocity when it runs out of fuel; (c) find the maximum height the rocket reaches; (d) find the rocket’s velocity the instant before the rocket...
