How long does it take the ball to hit the ground? e) You push with a 2 N force on a box that weighs 7 N. A frictional force of 3N opposes the motion of the box. Calculate the acceleration of the box?
Researchers have measured the acceleration of racing greyhounds as a function of their speed; a simplified version of their results is shown. The acceleration at low speeds is constant and is limited by the fact that any greater acceleration would result in the dog pitching forward because of the force acting on its hind legs during its power stroke. At higher speeds, the dog’s acceleration is limited by the maximum power its muscles can provide. a. What is the agent of the force that causes the dog to accelerate?b. If the dog’s mass is 32 kg, what is the average force acting on it during its initial acceleration phase?c. How far does the dog run in the first 4.0 s?
The figure shows a block (mass mAmA) on a smooth horizontal surface, connected by a thin cord that passes over a pulley to a second block (mass mBmB), which hangs vertically. Ignore friction and the masses of the pulley and cord. (Figure 1). a) Determine the acceleration of the system? b) Determine the tension in the cord?
Classes are canceled due to snow, so you take advantage of the extra time to conduct some physics experiments. You fasten a large toy rocket to the back of a sled and take the modified sled to a large, flat, snowy field. You ignite the rocket and observe that the sled accelerates from rest in the forward direction at a rate of 13.5 m/s2 for a time period of 3.30 s. After this time period, the rocket engine abruptly shuts off, and the sled subsequently undergoes a constant backward acceleration due to friction of 6.15 m/s2. After the rocket turns off, how much time does it take for the sled to come to a stop? time: ? By the time the sled finally comes to a rest, how far has it traveled from its starting point? distance traveled: ?
A 20-kg monkey has a firm hold on a light rope that passes over a frictionless pulley and is attached to a 20-kg bunch of bananas. The monkey looks up, sees the bananas, and starts to climb the rope to get them. a. As the monkey climbs, do the bananas move up, down, or remain at rest? b. As the monkey climbs, does the distance between the monkey and the bananas decrease, increase, or remain constant?
