Q. A toy rocket, launched from the ground, rises vertically with an acceleration of 25 m/s2 for 11 s until its motor stops.
Disregarding any air resistance, what maximum height above the ground will the rocket achieve? The acceleration of gravity is 9.8 m/s2 .
Answer in units of km.
A bowling ball weighing 71.2 is attached to the ceiling by a 3.50 rope. The ball is pulled to one side and released; it then swings back and forth like a pendulum. As the rope swings through its lowest point, speed of the bowling ball is measured a..
A 75 , 33 long rod hangs vertically on a frictionless, horizontal axle passing by its center. A 12 ball of clay traveling horizontally at 2.6 hits and sticks to the very bottom tip of the rod.
A simple pendulum has a mass of 0.350 kg and a length of 7.00 m. It is displaced through an angle of 12.0° and then released. Solve this problem by using the simple harmonic motion model for the motion of the pendulum.
A 41-kg box is thrown at a speed of 220 m/s & is brought to a halt in a collision that lasts for a time of 6.5 m/s. Find the magnitude of the average net force that acts on the box during the collision.
A shotgun fires a large number of pellets upward, with some pellets traveling very nearly vertically and others as much as 1.0o from the vertical. suppose that the initial speed of the pellets is uniformly 150ms-1 and ignore air resistance.
