A small asteroid that has a mass of 100 kg is moving at 200 m/s when it is 1110 km above the Moon. 1) How fast will the meteorite be traveling when it impacts the lunar surface if it is heading straight toward the center of the Moon? (Express your answer to three significant figures.) 2) How much work does the Moon do in stopping the asteroid if neither the Moon nor the asteroid heats up in the process? (Express...

S m 6. (19 points) A projectile of mass m= 2.00kg is fired at an asteroid of mass M = 400kg at a speed of vo = 1000 in the direction shown. The asteroid breaks into two pieces, m = 100kg and m2 = 300kg. The final speeds of the asteroid pieces are v, =10.00 and v, = 5.00 in the S directions shown. What are the final speed and direction of the velocity of the projectile after the collision?...

Th figure below shows a mass m=1.0 kg which is initially moving
with speed v=7.2 m/s at the top of a frictionless hill of height
h=4.9 m. It slides down the hill until it encounters a flat section
with unknown coefficient of kinetic friction µk. If the object
travels a distance D=11.1 m before reaching a speed of v/2, what is
the coefficient of kinetic friction µk? (use picture, but first
question)

A 110 kg running back carries the ball south at 8 m/s. A 130 kg linebacker runs to make the tackle going north at 5 m/s. In their collision, the linebacker wraps his arms around the runner and makes it an inelastic collision. How fast are they moving right after the collision (before they fall to the ground)? 3. A 2000 kg SUV traveling at 7 m/s south runs into the rear end of an 800 kg compact car sitting...

A 0.1 kg bullet initially travels at 200 m/s before striking the
edge of a uniform horizontal cylinder supported by a frictionless
axle through its center. The cylinder has a mass of 3 kg, a radiuis
of 0.5 m and is initially at rest. The bullet becomes lodged inside
the outer edge of the cylinder. PLEASE SHOW THE STEPS

A 73.3-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 8.61 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 below. What is the common speed of the players, immediately after...
