- A 75.1-kg person diving into a pool enters the water vertically at 8.29 m/s. The water exerts an average net force of 1294 N on the diver for 0.377 s. What is the speed of the diver after this time period? Add your answerA 15 kg block is on a 25kg block, and the 25 kg block is on a frictionless table. The coefficient of friction between the blocks are static-0.4 and kinetic=0.2 A horizontal applied force acts on the 25kg block. 15 Kg 25 Kg Fapplied Instead assume that the applied force is 20N and the blocks move together. The 15 kg block does not slip relative to the 25kg block. Determine the magnitude of the friction force acting on the 15 kg block Answer in newtons.Four objects are situated along the y axis as follows: a 1.94-kg object is at +3.01 m, a 3.06-kg object is at +2.54 m, a 2.54-kg object is at the origin, and a 4.09-kg object is at -0.505 m. Where is the center of mass of these objects? %3D m

Friction is negligible. The person sitting in the wagon is holding a rock. The total mass of the wagon, rider, and rock is 95.0 kg. The mass of the rock is 0.342 kg. Initially the wagon is rolling forward at a speed of 0.510 m/s. Then the person throws the rock with a speed of 15.3 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.

The coefficient of kinetic friction between the puppy and the surfboard is 0.400. The surfboard skims without friction across the water. (a) How fast will the puppy skim across the water after jumping on the surfboard? (b) How much time will it take for the puppy to stop sliding on top of the surfboard after jumping onto the surfboard? (c) How far will the puppy slide on top of the surfboard?
- Example B: Three people stand around not doing their physics homework as shown below. Find the distance of the center of mass of the 3 person system from leftmost person. M₁= 70 kg 4 m M₂=60 kg 6 m M₂= 82 kgThe upper mass is moving to the right with an initial velocity of 3 m/s. How far will mass A move before the system comes to rest if the coefficient of kinetic friction is 0.5. Set g=10m/s2. mass A=10 kg, mass B=5 kg1. A large semi truck has a mass of 35,000 kg. It collides head on with a car that has a mass of 1000 kg. The car’s initial velocity is 10 m/s and the truck’s initial velocity is 5 m/s in the opposite direction. What can you say about the forces and velocities of the two vehicles? a) The force that the truck makes on the car is much larger than the force the car makes on the truck so the car’s velocity changes much more than the truck’s does. b) The force that the truck makes on the car is equal to the force the car makes on the truck so the car’s velocity changes by the same amount that the truck’s velocity does. c) The force that the truck makes on the car is equal to the force the car makes on the truck but the mass of the truck is much larger than the car so the car’s velocity changes by much more than the trucks does. d) The mass of the truck is so much larger than the car that the force of the truck on the car is much greater than the force the car puts on the truck and the car…
- 1A 42-kg skater is standing still in front of a wall. By pushing against the wall she propels herself backward with a velocity of -2.8 cm/s. Her hands are in contact with the wall for 0.80 s. Ignore friction and wind resistance. Find the average force (in N) she exerts on the wall (which has the same magnitude, but opposite direction, as the force that the wall applies to her).Please help
