- A 56 g base ball is travelling at 40 m/s. When it hits with the baseball bat, you exert an average force of 78 N, sending the ball back at 30 m/s. How long was the baseball in contact with the bat? Please answer in m/sA 3.00-g bullet is fired horizontally into a 10.0-kg block of wood suspended by a rope from the ceiling. The bullet becomes embedded in the wood, and, as the result, the block swings up in an arc, like a ballistic pendulum, rising 3.00 mm above its original position. Which of the following is the closest to the initial speed of the bullet? Group of answer choices a. 235 m/s b. 24.3 m/s c. 75.0 m/s d. 811 m/s e. Cannot be determined since the heat generated in the collision is unknownA block of mass m1 = 15.5 kg slides along a horizontal surface (with friction, μk = 0.29) a distance d = 2.65 m before striking a second block of mass m2 = 5.25 kg. The first block has an initial velocity of v = 9.25 m/s. What is the speed of m1, in m/s, right before it collides with m2? Assuming that block one stops after it collides with block two, what is block two's velocity after impact in m/s?
- A knife thrower throws a knife toward a 300 g target that is sliding in her direction at a speed of 2.30 m/s on a horizontal frictionless surface. She throws a 22.5 g knife at the target with a speed of 38.0 m/s. The target is stopped by the impact and the knife passes through the target. Determine the speed of the knife (in m/s) after passing through the target.A 7.00 g bullet is fired horizontally into a 1.20 kg wooden block resting on a horizontal surface. The coefficient of kinetic friction between block and Part A surface is 0.20. The bullet remains embedded in the block, which is observed to slide 0.390 m along the surface before stopping. What was the initial speed of the bullet? Express your answer with the appropriate units. HÀ ? Value Units V = Submit Previous Answers Request AnswerAn unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only a rope and a bag of tools. First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion, away from the space station. The astronaut has a mass of ma = 102 kg and the bag of tools has a mass of mp = 19.0 kg. If the astronaut is moving away from the space station at Vj = 2.10 m/s initially, what is the minimum final speed vp.f of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever? Ub.f = m/s
- 1. A bullet of mass m, = 0.0500 kg is fired into a block of wood of mass m₂ = 0.850 kg. This block of wood is hanging from light wires. The bullet embeds in the block and the bullet and block combined swing up to a height of h=0.350 m. What was the speed of the bullet (vu) right before it hit the block of wood (ignore friction)? a. 4.64 x 10³ m/s b. 2.62 m/s c. 44.5 m/s d. 47.1 m/s e. 123 m/sA 1.00×104 kg railroad car is rolling at 3.00 m/sm/s when a 6000 kg load of gravel is suddenly dropped in.

Express your answer with the appropriate units(m/s).A 0.05 kg ball strikes a wall with a velocity v1 = -25 m/s and bounces back with a velocity v2 =5 m/s. If the collision lasts 0.2 s, then find the average force (in N) exerted on the ball.
- A gun fires a bullet vertically into a 1.40-kgkg block of wood at rest on a thin horizontal sheet. If the bullet has a mass of 13.5 g and a speed of 310 m/s, how high will the block rise into the air after the bullet becomes embedded in it? Answer in meters.A 59.5 kg man standing on a frictionless surface pushes two large boxes in opposite directions as shown. Initially everything is a rest. If the left box has mass 41.5 kg and final speed 3.25 m/s, and the right box has mass 27.0 kg and final speed 2.00 m/s, what is the final velocity (magnitude and direction) of the man? Let the positive direction be to the right.A 6.0 kg car is sitting on a floating 10 kg container in a lake and initially at rest 1.2 m away from the park. If the cat jumps back to the park, what is the minimum recoil speed of the box in the opposite direction? Assume the water and air friction are negligble and the dog travels in projectile motion.
