Question 3:   A 5.0 kg ball is rolling north at 2.50 m/s when it collides with a 6.0 kg ball which is initially at rest. Write the equations you would use to find the velocities of the balls in question 3 if the collision were instead perfectly elastic

In order to answer this question, follow the steps provided and remember that the total initial momentum of the system must equal the total final momentum. Also, remember that momentum and velocity are vector quantities so you must specify a negative sign if the motion is to the left. A green truck of mass 2500 kg travels to the right with a velocity vig = 3.7 m/s. The green truck approaches a red truck with mass 1460 kg that is traveling to the left with a velocity of vir = -3 m/s. The trucks collide and stick together after the collision. What is the final velocity, vf of the green-red truck system after the collision. (look at the figure/picture)(a) What was the initial momentum of the green truck before the collision?pgi = 9250 kg m/s(b) What was the initial momentum of the red truck before the collision?pri = -4380 kg m/s(c) What was the total initial momentum of the system of trucks?pTf = 4870 kg m/s (d) What must be the total final momentum of the system after the collision if…

Determine the unknown velocity value. Assume that the collisions occur in an isolated system.

Assume that the mass of the bullet, m1, is 4.97 g, the mass of the pendulum, m2, is 1.029 kg, and h is 4.71 cm. (a) Find the velocity of the system after the bullet embeds in the block. m/s(b) Calculate the initial speed of the bullet. m/s

A rifle of 8 kg lying on a smooth table discharges accidentally and fires a bullet of mass 11g with a muzzle speed of 422 m/s. What is the recoil velocity of the rifle?  Calculate answer to one decimal.

A child in a boat throws a 5.50-kg package out horizontally with a speed of 10.0 m/s. The mass of the child is 26.6 kg and the mass of the boat is 36.4 kg. Calculate the velocity of the boat immediately after, assuming it was initially at rest.Express your answer to three significant figures and include the appropriate units. Enter positive value if the direction of the velocity is in the direction of the velocity of the box and negative value if the direction of the velocity is in the direction opposite to the velocity of the box.

A rifle bullet with a mass of 10 g and moving with the speed of 300 m/s strikes and embeds itself in a block with a mass of 990 g that rests on a frictionless, horizontal surface and is attached to a coil spring. If the force constant of the spring is 300 N/m, a) calculate the common final velocity of block and bullet after the collision (in m/s). Enter the number up to ONE decimal place b) what is the maximum compression (in meters) of the spring? Enter the number up to THREE decimal places M
