rts move together along a horizontal frictionless track. A spring coiled in the two carts is released, causing the carts to separate. The velocities of the efore and after this interaction are shown in the velocity-time graph below. -Cart I Velocity +++ T 1 1 I 1 T 1 1 -Cart 2- Time (s) sent this process with a momentum bar chart for the system consisting of o carts. iend says that Cart 1 has less mass than Cart 2 because it ends up with a speed after the cart's separate and p = mv. Is your friend correct? If not, their error.

A football of mass 500g approaches a players food at 4 m/s. The player kick it back along its original path, exerting a force of 45N opposite the direction of approaching ball. His foot is in contact with thr ball for 0.2s. Ignore the effect of friction. 1. Calculate the velocity at which the ball leaves the player's foot. 2. Calculate the change in momentum of the ball. 3. Use vector diagram to illustrate this change.

NIOM A 7-kg marble has a head-on collision with a 3-kg marble, initially at rest on a playing surface. The speed of the 7-kg_marble is reduced from 1.08 m/s to 0.75 m/s in the 'collision. What is the speed of 3-kg marble after the collision? O 梦 $ # a hp

Two objects, A and B, have the same size and shape. Object A is twice as massive as B. The objects are simultaneously dropped from a high window on a tall building. (Neglect the effect air resistance.) The objects will reach the ground at the same time but object A will have a greater ___. Choose all that apply. a. speed b. acceleration c. momentum d. none of the above quantities will be greater

The figure below shows the velocity-versus-time graph before and after the collision of two carts on a horizontal track. After the collision the carts stick together. Green and blue lines show the velocities of cart 1 and cart 2, respectively, before the collision. The black line shows the velocity of the carts joined together after the collision. Determine the ratio of the carts' masses ml/m2. 0 VIX V2x collision

Ted Cmass=4Okg) and fredCmass = 60kg)are Stationary on frictionless ice, as seen in the drauing Poelow. Fredis holding a 10kg medicine ball. Fred throws it at 5mls to Ted who catches it. Ted throws the ball back to Fred at 7m/s, and Fred Catches it Ted D→Fred a) what is Ted's speed after catching the ball and throwing it back to Ered? b)What is Fred's speed after catching the ball thrown' from Ted?

Help with this homework question would be great, thanks!

Elon Mask the astronaut has a total mass of 69.4 kg. While in space, he throws a 2.34 kg tool away from him at a speed of 3.67 m/s relative to his space ship. What will Elon Mask's speed be (relative to the space ship) after throwing his tool? Express your answer in two decimal places with units of m/s.

Draw a velocity vs. time graph for Cart A and Cart B. Cart A has a mass of 4 kg and is traveling at 6 m/s to the right. 2 seconds later, Cart A collides with an identical Cart B that is at rest. The carts stick together after the collision.
