If the collision is perfectly elastic, what will be the speed and direction of each ball after the collision?A 50 lb child runs at 2.0 m/s and jumps onto a shopping cart and holds on for dear life. The cart has a mass of 40 kg. Assuming the child rides on the cart after the collision. What is the speed of the child and shopping cart just after the child jumps on is? 3.Two objects are on a collision course. Object #1 has a mass of 13.4 kg and an initial velocity of 12.3 m/s i. Object #2 has a mass of 7.53 kg and an initial velocity of -3.69 m/s i. If the system is isolated and the objects stick together upon colliding, what amount of energy is lost in the collision? Assume that all quantities are good to 3 significant figures, All numeric answers should be entered rounded to 3 significant figure.

- Hi there! I need some help! I am really confused. I do not know how to solve this! A block of mass m = 4.4 kg, moving on frictionless surface with a speed vi = 9.2 m/s, makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 4.4 kg block recoils with a speed of vf = 2.5 m/s. Mass m is closest to: Thank you!A 49 kg boy on roller skates moves with a speed of 4 m/s.

- Two objects collide head-on (see figure below). The first object is moving with an initial speed of v1i = 7.94 m/s and the second object is moving with an initial speed of v2i = 10.00 m/s. Assuming the collision is elastic, m1 = 5.17 kg, and m2 = 6.29 kg, determine the final velocity of each object. (Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left. Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)A 17.8 kg sled is sitting at rest on level ice, and this sled is hit by another sled that is twice as massive.
