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

The three identical 2.5 Ib blocks slide on the horizontal smooth surface. Initially
block A is moving to the right at 9 ft/sec while B and C are at rest. Determine the velocity of
blocks after (a) first collision when A collides with B and move together to right. (b) second
collision when A and B collide with C move to right.

Two rolling carts are moving toward each other at the same speed. Cart 1 has a mass m1 =200g and Cart 2 has a mass m2 =400g. Draw a velocity vector v → for each cart. Momentum p → is a vector defined as p → = m v →. Draw a momentum vector for each cart. Then add the two momentum vectors together to find the total momentum, vector P total =vector p1 + vector p2
q12
You're playing pool and you line up a shot on the 3 ball. You want the 3 ball to be deflected by an angle o3=25 degrees at a velocity v3=1.3 m/s so that it will make it into a side pocket. What initial velocity must you give the cue ball in order to make this shot and what will be the velocity and angle of the cue ball following the collision? Recall that the mass of a cue ball is 0.17 kg and the mass of a 3 ball is 0.16 kg.
A collision analyst applies physics principles to reconstruct what happened at automobile crashes. Assume that during a head-on crash between two cars, the cars came to a stop, and a large component of a plastic bumper broke off one car and skidded along the highway shoulder leaving skid marks. What information could the analyst gather from the bumper component and from the skid marks it produced? What measurements would be needed to estimate the speed of the cars just before the collision, and how would they be used?
Please solve with detailed explanation. Thank you
Ball B is hanging from a cord of negligible weight. An identical ball A is measured 3m above the hanging ball and just touching the cord, is released from rest and acquires a velocity (V_o) before striking ball B. Assuming perfectly elastic impact and no friction, compute the A) magnitude of the velocity of ball A in terms of V_o or velocity before impact B.) direction of the velocity of ball A in terms of V_o or velocity before impact (note: should be in angle with respect to north, east, west, south)

A car of mass m moves with a speed of Vo. The driver suddenly sees another car, of mass 3m, sitting at rest. The driver slams on the brakes. The coefficent of kinetic friction between the car and the road is μk. a) How far away must the second car be if the first car is to stop exactly in time to avoid hitting it? b) Suppose the car is a distance of d/2 away where d is the distance you found in part (a). Find the momentum of the car as it collides with the car at rest. c) Use conservation of momentum to calculate the speeds of both cars after the collision.
