A 0.35 kg puck is initially stationary on an ice surface with negligible friction. At time t = 0, a horizontal force begins to move the puck. The force is given by = (12.2 - 3.10t2), with in newtons and t in seconds, and it acts until its magnitude is zero.
a) What is the magnitude of the impulse on the puck from the force between t = 0.600 s and t = 1.20 s?b) What is the change in momentum of the puck between t = 0 and the instant at which F = 0?

The driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with acceleration of -5.90 m/s2 for 4.45 s, With what speed does the car then strike the tree
After reaching his lowest point, he oscillates up and down, hitting a low point eight more times in 44.0. He finally comes to rest 22.0 below the level of the bridge. Illustrate what is the spring stiffness constant?
A car is traveling along a straight road at a velocity of +31.0 m/s when its engine cuts out. For the next ten seconds, the car slows down, and its average acceleration is a1.
A charge = 5.00 is placed at the origin of an xy-coordinate system, and a charge = -3.00is placed on the positive axis at 4.00, Find the direction of this force
Two wheels have the same mass and radius of 4.3 kg and 0.50 m, respectively. One has the shape of a hoop, Find the net external torque that acts on each wheel
Two identical blocks of mass m are connected by a cord of length l that runs over a massless frictionless pulley, as shown below. One mass sits on a frictionless horizontal table. Now suppose that the string has a total mass M, which is distributed u..
A 5.70-kg ball is dropped from a height of 12.0m above one end of a uniform bar that pivots at its center. The bar has mass 6.00kg and is 4.80m in length. At the other end of the bar sits another 5.10-kg ball, unattached to the bar. The dropped ball ..
