60. GO A wagon is rolling forward on level ground. Friction is neg-
ligible. The person sitting in the wagon is holding a rock. The to-
tal mass of the wagon, rider, and rock is 95.0 kg. The mass of the
rock is 0.300 kg. Initially the wagon is rolling forward at a speed of
0.500 m/s. Then the person throws the rock with a speed of 16.0 m/s.
Both speeds are relative to the ground. Find the speed of the wagon
after the rock is thrown directly forward in one case and directly
backward in another.

An 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 = 113 kg and the bag of tools has a mass of m the space station at v¡ = 1.80 m/s. = 10.0 kg. The astronaut is moving away from What is the minimum final speed Ubf of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever? Ub,f = m/s
4. A fisherman in a boat catches a shark with a harpoon. The shark struggles for a while and then becomes limp when at a distance of 300 m from the boat. The fisherman pulls the shark all the way to the boat by the rope attached to the harpoon. During this operation, the boat (initially at rest) moves 45 m in the direction of the shark. The mass of the boat is 5400 kg. What is the mass of the shark? Pretend that the water exerts no friction. (Hint: Friction is ignored, so there are no external forces, and the center of mass of the system (the shark and boat) should not move at all.) A) 953 kg B) 477 kg C) 318 kg from the left and of

10. A snowboarder starts at the top of a 160. m tall hill with a velocity of 3.00 m/s. The portion of the hill covered with snow is essentially frictionless, but the flat, horizontal section at the base of the hill covered with mud is not. If the snowboarder masses in at 80.0 kg, and the coefficient of kinetic friction between board and mud is 0.750, how much distance is required for the snowboarder to come to rest?
A 686 N park ranger uses a basket and a rope-pulley system to transport an injured sea turtle up to a plateau, as shown in the figure. The sea turtle and basket together have a mass of 50.0 kg. The ranger holds firmly onto the rope and walks away from the cliff, speeding up at a steady rate of 0.300 m/2 2. He thereby causes the basket (and the turtle) to accelerate straight upwards at the same rate. Assume that the rope has negligible weight and that the pulley is ideal, having no friction in its bearing. Also assume that as the ranger trudges along, his feet do not slip on the ground. +x 26. The tension in the rope is equal to A. 490 N. B. 686 N. C. 475 N. D. 505 N. E. 196 N. 27. The frictional force which the ground exerts on the ranger's feet has a magnitude of C. 526 N. A. 490 N.

9. A 1200 kg car drives at an initial velocity vo = 45 m/s along a highway. At t = 0, the driver releases the gas, and the car slows to a stop due to a drag force given by Fdrag = -b v, where b = 15 kg/s³. Derive a function for the car's velocity as a function of time and solve it for the car's velocity at 10, 20, and 30 s.
Georgia, my blind and deaf pug/bulldog mix, tends to run full force through our back door. When I let her in, she doesn't see me and she runs at an acceleration of 11.5 m/s2 and a force of 212 Newtons into my chin (which hurts really badly when she does that). What is her mass, in kilograms? Round to two decimal places.
Daredevil Darla has heard that to avoid injury when jumping out of her rocket she should bend her knees upon landing. Darla has a mass of 74 kg. If just before contact with the ground, she has a downward speed of 7.3 m/s, then. . . (a) In a stiff -legged landing she comes to a halt in 2.0 ms. Find the average net force that acts on her during this time. ( b) When she bends her knees, Darla comes to a halt in 0.10 s. Find the average net force now. (c) During the landing, there are two forces acting on Darla: the normal force from the ground points upward, while her weight force points downward. The average net force acting on Darla includes both of these forces. Taking into account the directions of the forces, find the force of the ground on Darla in parts (a) and (b).

Hi please help with the following: After hitting a long fly ball that goes over the right fielder's head and lands in the outfield, the batter decides to keep going past second base and try for third base. The 59 kg player begins sliding 3.40 m from the base with a speed of 4.35 m/s. If the player comes to rest at third base, what was the coefficient of kinetic friction between the player and the ground?
