A student throws a 120 gram snowball at 7.5 m/s at the side of the schoolhouse, where it hits and sticks. What is the magnitude of the average force on the wall is the duration of the collision is 0.15 seconds?

A 0.250 kg toy car moving with a speed of 0.820 m/s collides with a wall. The figure shows the force exerted on the car by the wall over the course of the collision. What is the magnitude of the velocity, or final speed, of the car after the collision?

Two toy cars with masses of 0.70 kg  and 0.30 kg, respectively, move towards each other and collide  head-on and then stick together.. The magnitude of the initial velocity for each of of the toy cars is 15.0 m/s. What is the speed of the toy cars  immediately after collision?

The two collars have the masses and initial velocities shown in the figure. The coefficient of restitution for the collision is e=0.5, and friction is negligible. a) Determine the velocity of the two collars after impact. b) If the time duration of the collision is 0.025 s, determine the average impact force. V₁ = 7 m/s V₂ = 5 m/s m₁ = 2 kg m₂ = 3 kg

Problem 4: Suppose a lump of clay has a mass of 0.2 kg and it slides without friction across ice at a speed of 0.75 m/s. It collides with another lump of clay that is at rest and that has a mass of 0.35 kg. If the two lumps of clay stick together, what is their speed after the collision?

Block A of mass m = 1.48 kg moving on a horizontal plane with velocity of vj = 1.71 m/s collides with Block B of the same mass at rest before the collision. After the collision, Block A stops. What is the velocity of Block B Vf after collision? Assume there is no friction between the blocks and the horizontal plane. Keep three significant figures for the answer.

A 1500 kg aircraft going 35 m/s collides with a 2000 kg aircraft that is parked and they stick together after the collision and are going 15 m/s after the collision. If they skid for 123.9 m before stopping, how long (in seconds) did they skid?

An object with a mass of 8.00 g is moving to the right at 14.0 cm/s when it is overtaken by an object with a mass of 25.0 g moving in the same direction with a speed of 17.0 cm/s. If the collision is elastic, determine the speed of each object after the collision in centimeters per second. 25.0 g object_______________ cm/s   8.00 g object _______________ cm/s

Particle 1 has mass m1= 2 kg and velocity v1= 10 m/s . It collides with particle 2 which has mass m2= 20 kg and velocity = -4 m/s. If the velocity of particle 2 after the collision is v2 = - 1.5m/s a. Find the velocity ( ) of particle 1 after the collision. b. Draw a diagram(arrows) representing the masses and velocities before and after the collision.

The drawing shows a collision between two small balls. Ball (1) has a mass of 140 g and is moving along the x-axis with a velocity of 4.60 m/s. It makes a collision with ball (2), which has a mass of 210 g and is initially at rest. After the 60°). What is the magnitude of %D collision, the two balls fly apart with angles as shown in the figure below (a = 58° and B the velocity of ball (2) after the collision? m/s +y m2 m1 +x
