A 95.0 kg football player is standing on a sheet of ice, i.e., there is negligible friction betweentheir feet and the ground. A 0.400 kg football is travelling horizontally at 12.0 m/s towardsthe football player just before they try to catch the ball. (a) If they successfully catch the ball,then how fast does the player and the ball move horizontally after it is caught? (b) If the ballhits the player and bounces off of their chest moving at 8.50 m/s in the opposite direction,then what is the speed of the player after the ball bounces off of their chest? (c) Include adiagram of each of the situations. [Diagram 3 pts.]

Kyle, a 80.0 kg football player, leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg ball precisely at the peak of his jump, when he is 0.437 m off the ground. He hits the ground 0.0358 m away from where he leapt. If the ball was moving horizontally when it was caught, how fast u was the ball traveling? Vs m/s
A cue ball travelling at 0.785 m/s [270°] strikes a stationary five-ball, causing it to move at 0.601 m/s [230°]. The cue ball and the five-ball each have a mass of 160 g. What will be the velocity of the cue ball immediately after impact? Ignore frictional and rotational effects.
The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at ??,2=17.5 m/s when the eagle swoops down, grabs the pigeon, and flies off. At the instant right before the attack, the eagle is flying toward the pigeon at an angle θ=47.1° below the horizontal and a speed of ??,1=42.1 m/s. What is the speed of the eagle immediately after it catches its prey? Speed: What is the magnitude of the angle, measured from horizontal, at which the eagle is flying immediately after the strike? Magnitude of angle:
The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at ??,2=16.1 m/s when the eagle swoops down, grabs the pigeon, and flies off.

Identical twins, each with mass 52.5 kg, are on ice skates and at rest on a frozen lake, which may be taken as frictionless. Twin A is carrying a backpack of mass 12.0 kg. She throws it horizontally at 2.55 m/s to Twin B. Neglecting any gravity effects, what are the subsequent speeds of Twin A and Twin B?

An automobile with a total mass of 1500 kg is placed on a moving flatbed railcar. The flatbed is 1.20 m above the ground. The railcar is moving eastward at a constant speed of 8.2 m/s and has a mass of 38000 kg. The car accelerates westward and when it leaves the flatcar it is traveling at 23.0 m/s relative to the ground. (a) What is the speed of the railcar when the car leaves? (b) What is the distance between the car and the west end of the flatcar, when the car touches the ground?
Answer must be in nanometers.
A wagon is rolling forward on level ground. Friction is negligible. The person sitting in the wagon is holding a rock. The total mass of the wagon, rider, and rock is 99.5 kg. The mass of the rock is 0.277 kg. Initially the wagon is rolling forward at a speed of 0.488 m/s. Then the person throws the rock with a speed of 16.6 m/s. Both speeds are relative to the ground. Find the speed of the wagon after the rock is thrown (a) directly forward in one case and (b) directly backward in another. (a) vi (b) v-
Spheres A (mass 0.040 kg), B (mass 0.060 kg) and C (mass 0.080 kg) are approaching the origin as they slide on a frictionless air table.

A delivery person carries a stack of three boxes labeled 1, 2, and 3. Box 3 is on the bottom of the stack, and box 1 is on the top. The masses of boxes 1, 2, and 3 are m = 3.5 kg, m2 = 4.5 kg, and m3 = 8.0 kg, respectively. The delivery person places the stack of boxes on an elevator floor, which then accelerates upward with a magnitude of a = 0.90 m/s?. Assume that the positive direction is up. Calculate the contact force F1-2 that box 1 exerts on box 2 during the acceleration. F-2 = N %3D Calculate the contact force F3-2 that box 3 exerts on box 2 during the acceleration. F3-2 = N
A basketball of mass 764 g is thrown horizontally and is caught by a player of mass 75 kg, and the ball comes to rest after 0.56 s. If the average horizontal force of the ball on the player was 13.2 N, calculate the initial speed (in m⋅⋅s-1) of the ball.
