A 10-kg cart moving to the right at 5 m/s has a head-on collision with a5-kg cart moving to the left at 7 m/s. If the carts stick together, what is the velocity of the combination?
A 10-kg box is sliding across an ice rink at 10 m/s. A skater exerts a constant force of 10 N against it. How long will it take for the box to come to a complete stop?
A stationary curling stone is struck in a glancing collision by a second curling stone of equal mass. If the first stone moves away at a velocity of 0.92m/s [N71degreesW] and the second stone moves away at a velocity of 1.25m/s [N44degreesE], what is the
A 0.5-kg object has a momentum of 10 kg.m/s. What is its speed?
A 3 ton Toyota land cruiser travelled at a speed of 45m/s, collides with a 2 ton comfort taxi which was parked in front of the traffic lights intersection. After the collision, both cars lock together and move off in one direction. Determine a) the speed
A 150-kg halfback is running down the field carrying the ball at a velocity of 5 m/s. A 50-kg linebacker from the opposing team is running at him in the opposite direction. The linebacker hopes to wrap him in a tackle
Measurements and calculations from a slow motion video show a 50.0-g ball hitting the ground at +5.0 m/s and bouncing back up at -4.0 m/s. By how much did the balls momentum change?
A bullet has a mass of 50 g, and its momentum is 25 kg.m/s. What is the velocity of the bullet?
Not too long ago, an interesting thing happened at the Canadian Open Golf Tournament. Tiger Woods bounced his tee shot off of a young spectator’s head in the last round of the tournament. The ball made contact for 0.08 seconds, and struck the boy’s head a
