Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

Definition Definition Force that opposes motion when the surface of one item rubs against the surface of another. The unit of force of friction is same as the unit of force.

A 6-g bullet is shot into a 2.1-kg block of wood, where it becomes embedded. The block is initially at rest and the bullet has an initial velocity of 400 m/s. The block then travels 1.2 m horizontally. What is the coefficient of kinetic friction between the block and the surface?
A tennis ball is flying east towards the wall with a speed of 41.3 m/s. After bounced against the wall, it's flying west with a speed of 26.3 m/s. If the mass of the ball is 0.1 kg, and the time of collision with the wall is 0.099 seconds, what is the magnitude of the force on the wall during this process in unit of Newton?
A 2.50 kg box sits halfway up a 16.0 m long ramp that is inclined at an angle of 16.00. You shove a second box, of mass 1.50 kg, that's at the bottom of the ramp, so that it starts sliding up the ramp with a speed of 20.0 m/s. It hits the first box, sticks to it, and they both continue to slide up the ramp. The coefficient of kinetic friction between the boxes and the ramp is 0.200. Where, from the bottom of the ramp, do they come to rest?
A pickup truck is moving at 25 m/s with a toolbox of mass m resting on the bed of the truck 2.8 m behind the cab. Suddenly the brakes are applied, causing the toolbox to slide, and the truck comes to a stop in 4.8 s. The coefficient of kinetic friction between the toolbox and the bed of the truck is 0.4. After the brakes are applied, how much time elapses before the toolbox strikes the cab?
A tennis ball is flying east towards the wall with a speed of 32.5 m/s. After bounced against the wall, it's flying west with a speed of 26.3 m/s.

You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 43.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 20.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750. How fast (in miles per hour) was car A traveling just before the collision? (This problem uses English units because they would be used in a U.S. legal proceeding.) speed of car A: mph
A 50.0 g ball is shot in the horizontal direction, aimed directly at a wall. The initial speed of the ball is 13.0 m/s, whereas when the ball bounces back, it is moving at 12.0 m/s in the opposite direction. If the contact between the ball and the wall lasts t=0.250 s, what is the strength of the force the wall exerts on the ball? Give your answer in units of newtons, to three significant figures.
