A 10.0 N force is applied to a 100kg box on a frictionless surface. What would the acceleration be?

A commercial airplane is coming in for a landing. Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?

A 400 g block with an initial speed of 80 cm/s slides along a horizontal tabletop against a friction force of 0.70N. (a) How far will it slide before stopping? (b) What is the coefficient of friction between the block and the tabletop?

A horizontal force is applied to an object weighing 392 N that causes its speed to increase uniformly from 0 m/s to 6 m/s in 3 seconds. If we disregard the friction value, calculate the applied force

A 1,300kg car is traveling at a velocity of 30.0m/s when the driver slams on the brakes. If a constant force of kinetic friction of magnitude 9,200N acts on the car, how far does the car travel when it comes to a stop

A 4.0kg object is moving across a friction-free surface with a constant velocity of 2ms–1. How much the horizontal forces is needed to maintain this state of motion?

A ball with mass 0.3 kg is thrown upward with initial velocity 10 m/s from the roof of a building 50 m high. Assume there is a force due to directed opposite to the velocity, air resistance of magnitude 1325 where the velocity v is measured in m/s. NOTE: Use g-9.8 m/s as the acceleration due to gravity. Round your answers to 2 decimal places. a) Find the maximum height above the ground that the ball reaches. Height: m b) Find the time that the ball hits the ground. Time: seconds c) Use a graphing utility to plot the graphs of velocity and position versus time.

An 80 kg skier sliding across a flat smooth ice surface at 20 m/s reaches a flat muddy surface with a coefficient friction of 1.2. How far does she travel before stopping

On September 8, 2004, the Genesisspacecraft crashed in the Utah desert because its parachute did not open.The 210 kg capsule hit the ground at 311 km/h and penetrated the soilto a depth of 81.0 cm. How long did this force last?

A 10.1 kg box is released on a 49.9° incline and accelerates down the incline at 0.07 m/s². What is the coefficient of kinetic friction between the two surfaces?
