A 4.00 g bullet travelling horizontally with a magnitude of 440 m/s is tired into a wooden block with a mass of 0.80 kg intitially st rest on a level surface. The bullet passes through the block and emerges with its speed reduced to 160 m/s. With the info, what physics concept is the one that allows us to determine the speed of the block just after the bullet has passed through the block?

A car's bumper is designed to withstand a 5.76 km/h (1.6-m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.210 m while bringing a 890 kg car to rest from an initial speed of 1.6 m/s.

Tarzan (80 kg) drops from a height of 2.5 m to swing down and pick up Jane.  If he picks up Jane (60 kg) with an inelastic collision, determine the following. The velocity just before picking up Jane. (7.1 m/s) The velocity just after picking up Jane.  (4.04 m/s) The percentage of energy lost when picking up Jane.  (43%) The height (h), after picking up Jane.  (0.82 m)

An outfielder throws a 0.150 kg baseball at a speed of 26.0 m/s and an initial angle of 30.0°. What is the kinetic energy of the ball at the highest point of its motion? upuonal) ?

Current Attempt in Progress In the figure here, a stationary block explodes into two pieces L and R that slide across a frictionless floor and then into regions with friction, where they stop. Piece L, with a mass of 3.3 kg, encounters a coefficient of kinetic friction u = 0.45 and slides to a stop in distance d = 0.33 m. Piece R encounters a coefficient of kinetic friction µr = 0.52 and slides to a stop in distance de = 0.46 m. What was the mass of the block?

A cars bumper is designed to withstand a 4.0km/h (1.1 -m/s) collision with an immovable object without damaging the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.185m while bringing a 875kg car to rest from an initial speed of 0.85m/s in newtons.
