28. After sliding down a snow-covered hill on an inner tube, Ashley is coast- ing across a level snowfield at a constant velocity of +2.7 m/s. Miranda runs after her at a velocity of +4.5 m/s and hops on the inner tube. How fast do the two slide across the snow together on the inner tube? Ashley's mass is 71 kg and Miranda's is 58 kg. Ignore the mass of the inner tube and any friction between the inner tube and the snow.

A bullet of mass 2 kg is headed at horizontal speed 60 m/s toward a block of mass14(2 kg) = 28 kg resting on a horizontal frictionless surface. The bullet strikes the blockand comes to rest relative to the block somewhere deeply embedded inside the block.What average force did the block exert onthe bullet while it was coming to a stop insidethe block, if the stopping process took 0.04 s? 1. −200 N2. Not enough information is provided toanswer.3. −2800 N4. 3000 N5. 200 N6. 2800 N7. −3000 N8. Zero, since the bullet comes to rest relative to the block.
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
A student designs a water powered rocket. The rocket expels 2000 mL (2.0 kg) of water in 3.0 seconds at a speed of 50 m/s. The empty bottle has a mass of 200 g. What is the thrust the rocket experiences? How much fuel (in kg) does the rocket need to lose to lift off
An object attached to a rope is released from rest where the rope is in a horizontal position. At the lowest point in its swing, a bullet moving in the opposite direction hits the block and lodges deeply into it. As a result of this impact, both the bullet and the block are stationary. What is the magnitude of the bullet's velocity just befote hitting the block? Take the mass of the block to be 2.0 kg, the mass of the bullet to be 8.0 g and the length of the rope to be 1.8 m.
Lions can run at speeds up to approximately 80.0 km/h. A hungry 109 kg lion running northward at top speed attacks and holds onto a 39.0 kg Thomson's gazelle running eastward at 75.0 km/h. Find the final speed ?fvf of the lion‑gazelle system just after the lion attacks. vf=? in m/s
An ice skater with mass = mi goes skating while carrying a bag of sand with initial mass = m0 . At one point, she gives herself a constant initial velocity v0 , and then slowly pours the sand out of the bag at a constant rate κ. Is she speeding up or slowing down? Write out an expression for the velocity as a function of time. How long does it take for her velocity to change by a factor of 2? Your answer can include mi, m0, v0, and κ.
On the set of a new Hollywood movie, a 74.1-kg stunt actor (Max Payne) is tossed straight out of a helicopter hovering (stationary) at a height of 43.4 meters. The stunt actor is thrown from the helicopter at a speed of 4.17 m/s, eventually landing in the water below. Determine the stunt actor's impact speed and assume negligible air resistance. You can use the approximation that g = 10 m/s2.
Suppose you are navigating a spacecraft far from other objects. The mass of the spacecraft is 3.2 × 104 kg (about 32 tons). The rocket engines are shut off, and you're coasting along with a constant velocity of km/s. As you pass the location km you briefly fire side thruster rockets, so that your spacecraft experiences a net force of N for 23.0 s. The ejected gases have a mass that is small compared to the mass of the spacecraft. You then continue coasting with the rocket engines turned off. Where are you an hour later? (Think about what approximations or simplifying assumptions you made in your analysis. Also think about the choice of system: what are the surroundings that exert external forces on your system?) 7₁ = m
A hockey player slaps a puck into a cushion, which brings the puck to rest. If the puck's initial velocity was +40 m/s and it has a mass of 170 g, what force does the cushion apply to the puck? Assume the cushion acts on the puck for 0.03 s and the surface that the puck slides on is frictionless.
3. An m = 55 kg sprinter, when starting a race, pushes back horizontally on the starting block with an average F = 590 N force for a time interval of t =0.68 second. a. What is the speed, in m/s, of the sprinter at the end of the 0.68 s? b. What is the distance, in meters, the sprinter traveled during the 0.68 s time interval?
A billiard ball strikes and rebounds from the cushion of a pool table perpendicularly. The mass of the ball is 0.38 kg. The ball approaches the cushion with a velocity of +2.30 m/s and rebounds with a velocity of -1.70 m/s. The ball remains in contact with the cushion for a time of 3.40 × 10-3 s. What is the average net force (magnitude and direction) exerted on the ball by the cushion?
