- A 0.15 kg baseball is moving at 35 m/s toward home plate when it is hit with the bat. The ball is in contact with the bat for 0.0019 s, and leaves the bat at 25 m/s directly away from home plate. Determine the average force exerted by the bat on the ball..A car with a mass of 980 kg is initially traveling east toward an intersection with a speed of vc = 20.2 m/s and a 1500 kgpickup is traveling north toward the same intersection. The car and truck collide at the intersection and stick together. After the collision, the wreckage (car and truck) moves off in a direction of 43.0° above the x-axis. Determine the initial speed of the truck and the final speed of the wreckage in meters per second. initial speed of the truck m/sfinal speed of the wreckage m/s
- . A 1000-kg car traveling west at 30 m/s collides with a 1000-kg truck traveling south at 20 m/s. Theoccupants, wearing seat belts, are uninjured, but the two vehicles move away from the impact point as one. The insurance adjustor asks you to find the velocity of the wreckage just after impact. What is your answerKyle, 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/sJack (mass 56.0 kg) is sliding due east with speed 8.00 m/s on the surface of a frozen pond. He collides with Jill (mass 49.0 kg), who is initially at rest. After the collision, Jack is traveling at 5.00 m/s in a direction 34.0 degrees north of east. Ignore friction. What is the magnitude of the Jill's velocity, after the collision, as she travels at an angle of 35.95 degrees south of east?
- Suppose a clay model of a koala bear has a mass of 0.240 kg and slides on ice at a speed of 0.745 m/s. It runs into another clay model, which is initially motionless and has a mass of 0.310 kg. Both being soft clay, they naturally stick together. What is their final velocity (in m/s)? (Enter the magnitude.)Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York; there is negligible friction between his feet and the ice. A friend throws Olaf a ball of mass 0.400 kg that is traveling horizontally at 10.5 m/s. Olaf's mass is 72.8 kg. If Olaf catches the ball, with what speed vf do Olaf and the ball move afterward? If the ball hits Olaf and bounces off his chest horizontally at 8.40 m/sm/s in the opposite direction, what is his speed vf after the collision?A missile of mass 1.05 102 kg is fired from a plane of mass 5.20 103 kg initially moving at a speed of 2.50 102 m/s. If the speed of the missile relative to the plane is 1.11 103 m/s, what is the final velocity of the plane?
- A soccer player bounces the ball off her head, changing the velocity of the ball. She changes the x component of the velocity of the ball from vix = 8.70 m/s to vfx = 5.10 m/s and the y component from viy = −4.00 m/s to vfy = 2.70 m/s. If the ball has a mass of 0.450 kg and is in contact with the player's head for 7.10 ms, determine the following. (Assume that the +x axis is to the right and the +y axis is up along the page.) A. direction of the impulse delivered on the ball counterclockwise from the +x-direction. B. magnitude of the impulse delivered to the ball in ( kg * m/s)An object, in initially travelling 45° south of east at 100 m/s, explodes into three separate pieces. A 2.0 kg fragment travels due south at 105 m/s, while a 4.0 kg fragment travels due east at 155 m/s. The last fragment has a mass of 3.0 kg. The third fragment travels at an unknown velocity. Calculate its direction and magnitude of this unknown velocity.A baseball arrives at home plate at a speed of 43.3 m/s. The batter hits the ball along the same straight line directly back at the pitcher at 68.4 m/s (think about the directions). The baseball has a mass of 0.145 kg and the bas is in contact with the ball for 6.28x10^-4 s. What is the magnitude of the average force on the ball from the bat?
