An object with a mass of 1.76 kg is initially at rest upon a horizontal, frictionless surface. An applied force of 3.04 N i acts on the object for 2.08 s. What is the object's final speed? Enter a number rounded to 2 decimal places and assume the answer has proper SI Units

A boy pulls a bag of baseball bats across a ball field toward theparking lot. The bag of bats has a mass of 6.80 kg, and the boyexerts a horizontal force of 24.0 N on the bag. As a result, the bagaccelerates from rest to a speed of 1.12 m>s in a distance of 5.25 m.What is the coefficient of kinetic friction between the bag and theground?

A box of mass 2.0 kg hangs by a cable from the ceiling of an elevator. The elevator is moving up at a steady speed of 8.0 m/s for 15 m. Use g = 10 m/s2.

A 400. kg cart slides along the track shown in the image, beginning at point A. It starts from rest and experiences no friction or air resistance. Once it gets to the point marked B, what is the cart’s speed AND the value of the normal force? Because of HuskyCT's limitations with multiple answer questions, please enter your two answers as numbers only, and with exactly 2 significant figures each.   The cart has a speed of ----- ??m/s. The value of the normal force at point B is  ------- ?N.

A 50 g  particle that can move along the  x-axis experiences the net force Fx=2.0t^2 N where t  is in s. The particle is at rest at t = 0 s What is the particle's speed at tt = 2.6 ss? v=________

Whether or not an object (such as a plate, glass, or bone) breaks upon impact depends on the average force exerted on that object by the surface. When a 2.5 kg glass figure hits the floor, it will break if it experiences an average force of 538 N. When it hits a tile floor, the glass comes to a stop in 0.020 s. From what minimum height (in m) must the glass fall to experience sufficient force to break? m How would your answer change if the figure were falling to a padded or carpeted surface? Explain. The duration of the collision would be shorter, so the average force for a given change in momentum would be more.The duration of the collision would be longer, so the average force for a given change in momentum would be less.     The duration of the collision would be longer, so the average force for a given change in momentum would be more.The duration of the collision would be shorter, so the average force for a given change in momentum would be less.

A 500 g particle has velocity vx = -8.0 m/s at t =-2 s. Force Fx=(4−t^2)N, where t is in s, is exerted on the particle between t=−2s and t = 2 s. This force increases from 0 N at t = -2 s to 4 N at t = 0 s and then back to 0 N at t = 2 s. What is the particle's velocity at t=2 s?

An object of mass m= 7.6 kg is free to move on a horizontal surface without any friction. It is initially at rest and starts moving under a net force of F =(3N)î +(4N)ĵ . What is the object's speed in m/s after moving 1 meter?

Sam, whose mass is 74.0 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 220.0 N and a coefficient of kinetic friction wtih the snow of 0.07. Unfortunately, the skis run out of fuel after only 11.5 seconds. What Sam's top speed (in m/s) assuming that the acceleration due to gravity is 9.80 m/s2? How far (in m) has Sam traveled when he finally coasts to a stop?

7. An 8.00 kg block is released from rest and slides 1.60 m down a 40° slope. Its speed at that point is 4.00 m/s. Find the magnitude of the frictional force on the block. 'i= 0 m/s V2= 4 m/s 1.6 m 40°
