A 90.0 kg fullback running 36.9° north of east with a speed of 5.00 m/s is tackled and held onto by an 90.3 kg opponent running north with a speed of 2.07 m/s. What is the magnitude of the velocity of the players immediately after the tackle?

A 1400 kg car moving at 21 m/s runs into a 1200 kg car mobing in the same direction at 14 m/s. The two Cars lock together, and both drivers inmediately apply their brakes. If the cars comes to rest in 18 m, what is the coefficient of friction between the car's tires and the road?

Albert and his friend Isaac are standing in the middle of a sheet of ice in the student parking lot when they decide to give each other a push. If Albert has a mass of 73.6 kg and moves to the right at 1.30 m/s after the push, how fast will Isaac move if his mass is 51.8 kg? m/s

A tennis ball is flying east towards the wall with a speed of 40.3 m/s. After bounced against the wall, it's flying west with a speed of 28.2 m/s.  If the mass of the ball is 0.1 kg, and the time of collision with the wall is 0.033 second, what is the magnitude of force on the wall during this process in unit of Newton?

A hockey stick exerts an average force of39 N[S] on a 0.20 kg hockey puck over a displacement of 0.22 m. If the hockey puck started from rest, what is the final velocity of the puck? Assume that the friction between the puck and the ice is negligible.

On the set of a new Hollywood movie, a 74.1-kg stunt actor (Max Payne) is tossed straight out of a helicopter hovering (stationary) at a height of 43.4 meters. The stunt actor is thrown from the helicopter at a speed of 4.17 m/s, eventually landing in the water below.  Determine the stunt actor's impact speed and assume negligible air resistance. You can use the approximation that g = 10 m/s2.

A 48.1-kg person, running horizontally with a velocity of +3.23 m/s, jumps onto a 16.8-kg sled that is initially at rest. (a) Ignoring the effects of friction during the collision, find the velocity of the sled and person as they move away. (b) The sled and person coast 30.0 m on level snow before coming to rest. What is the coefficient of kinetic friction between the sled and the snow? (a) Number i (b) Number i Save for Later Units Units Attempts: 1 of 3 used Submit Answer

A 0.6 Kg football is thrown with a velocity of 22 m/s to left. A stationary receiver catches the ball and brings it to rest in 0.03 s. What is the force exerted on the ball by the receiver? Show the procedure, result with units and direction

A 76.1 kg astronaut of holding a 12.3 kg tool pack while drifting at 10.6 m/s to the right. She throws the tool pack away so that it is drifting at 1.5 m/s to the left. How fast is she moving after the throw? Assume that they are out in deep space with no other forces acting on them.

A car (VW) and a truck (C) collide inelastically (stick together). The impact is made in a very short time of t= 0.1 s. Initial speed Vvw=40.0 m/s Cv=30 m/s Masses mvw = 900.0 kg mc = 2000.0 kg Find the final velocity of the vehicles. Find the average acceleration of each vehicle Find the average force over each vehicle. Find the initial kinetic energy. Find the final kinetic energy.
