- A 1,220-kg car traveling initially with a speed of 25.0 m/s in an easterly direction crashes into the rear end of a 9,400-kg truck moving in the same direction at 20.0 m/s velocity of the car right after the collision is 18.0 m/s to the east. +25.0 m/s +20.0 m/s +18.0 m/s Before After (a) What is the velocity of the truck right after the collision? (Round your answer to at least three decimal places.) (b) How much mechanical energy is lost in the collision?A 45.0-kg skater is traveling due east at a speed of 2.50 m/s. A 70.0-kg skater is moving due south at a speed of 7.40 m/s. They collide and hold on to each other after the collision, managing to move off at an angle south of east, with a speed of vf. Find (a) the angle and (b) the speed vf, assuming that friction can be ignored. (a) Number i (b) Number i Units Units <A 50.0 kg penguin is skiing, her velocity is facing north at 5.0 m/s. She runs into a 28.0 kg sea lion. After they are moving together at (velocity) of 2.0 m/s with an angle of 40 degrees north of east. Find the magnitude of the sea lions velocity before the accident?
- A 78.9 kg linebacker (X) is running at 6.83 m/s directly toward the sideline of a football field. He tackles a 89.1 kg running back (O) moving at 9.27 m/s straight toward the goal line, perpendicular to the original direction of the linebacker. As a result of the collision, both players momentarily leave the ground and go out‑of‑bounds at an angle ϕ relative to the sideline, as shown in the diagrams. What is the common speed ?fvf of the players immediately after their impact? What is the angle ϕ of their motion relative to the sideline?16.) see photo for details, please provide full body diagram with solutionA 87 g ball moving at 118 cm/s collides head-on with a stationary 13 g ball. Determine the speed of the heavier ball after impact if the coefficient of restitution is 0.52. Express your answer in cm/s.
- What is the velocity (in m/s) of a 905 kg car initially moving at 25.0 m/s, just after it hits a 135 kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car. (Enter the magnitude.)Two football players collide head-on in midair while chasing a pass. The first player has a 95.0 kg mass and an initial velocity of 5.60 m/s, while the second player has a 114 kg mass and initial velocity of -3.7 m/s. What is their velocity (in m/s) just after impact if they cling together? (Indicate the direction with the sign of your answer.) m/s?A 6.75-kg bowling ball moving at 8.95 m/s collides with a 0.875-kg bowling pin, which is scattered at an angle of θ = 24.5° from the initial direction of the bowling ball, with a speed of 11.2 m/s. Calculate the magnitude of the final velocity, in meters per second, of the bowling ball.
- A 80.1 kg linebacker (X) is running at 6.71 m/s directly toward the sideline of a football field. He tackles a 91.7 kg running back (O) moving at 9.49 m/s straight toward the goal line, perpendicular to the original direction of the linebacker. As a result of the collision, both players momentarily leave the ground and go out‑of‑bounds at an angle ϕ relative to the sideline, as shown in the diagrams. What is the common speed ?f of the players immediately after their impact? What is the angle ϕ of their motion relative to the sideline?A 9230-kg truck collides head on with a 1250-kg parked car. The vehicles entangle together and slide a linear distance of 10.6 meters before coming to rest. Assuming a uniform coefficient of friction of 0.820 between the road surface and the vehicles, determine the pre-collision speed of the truck.A 0.150-kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.80 m/s. It has a head-on col- lision with a 0.300-kg glider that is moving to the left with a speed of 2.20 m/s. Find the final velocity (magnitude and direction) of each glider if the collision is elastic.
