A pitcher claims he can throw a 0.145-kg baseball with as much momentum as a 3.00-kg bullet moving with a speed of 1.50 103 m/s (a) What must the baseballs speed be if the pitchers claim is valid? (b) Which has greater kinetic energy, the ball or the bullet?
Gayle runs at a speed of 4.00 m/s and dives on a sled, initially at rest on the top of a frictionless, snow-covered hill. After she has descended a vertical distance of 5.00 m. her brother, who is initially at rest, hops on her back, and they continue down the hill together. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 50.0 kg, the sled has a mass of 5.00 kg, and her brother has a mass of 30.0 kg.
A child of mass m starts from rest and slides without friction from a height h along a curved waterslide (Fig. P5.46). She is launched from a height h/5 into the pool. (a) Is mechanical energy conserved? Why? (b) Give the gravitational potential energy associated with the child and her kinetic energy in terms of mgh at the following positions: the top of the waterslide, the launching point, and the point where she lands in the pool. (c) Determine her initial speed V0 at the launch point in terms of g and h. (d) Determine her maximum airborne height ymax in terms of h, g, and the horizontal speed at that height, v0x. (e) Use the x-component of the answer to part (c) to eliminate from the answer to part (d), giving the height ymax in terms of g, h, and the launch angle . (f) Would your answers be the same if the waterslide were not frictionless? Explain. Figure P5.46
On a 119 meter high roller coaster is a 75 kg car at rest. Assuming there is no friction, what will its velocity be at the bottom? a) The car from the previous roller coaster begins its journey towards a second climb with a speed of 58 m / s. Assuming there is no friction, how high will it reach before stopping?
A 2.1 ✕ 103-kg car starts from rest at the top of a 5.2-m-long driveway that is inclined at 24° with the horizontal. If an average friction force of 4.0 ✕ 103 N impedes the motion, find the speed of the car at the bottom of the driveway. m/s

A car's brakes do work to stop a car. Suppose a car is moving at 18 m/s and it has a mass of 2100 kg. A.) If the friction force from the brakes is 550 N, what is the stopping distance (in m)? B.) If the speed is doubled, what would the stopping distance (in m) be? C.) Complete the sentence with a number: When the speed of a car is doubled, the stopping distance is increased by a factor of?

Marbles of mass mm are thrown from the edge of a vertical cliff of height h at speed v0. a)Neglecting air resistance, how fast (in terms of m, h, and v0) will these marbles be moving when they reach the bottom of the cliff if they are thrown straight up? b)Neglecting air resistance, how fast (in terms of m, h, and v0) will these marbles be moving when they reach the bottom of the cliff if they are thrown straight down? c)Neglecting air resistance, how fast (in terms of m, h, and v0) will these marbles be moving when they reach the bottom of the cliff if they are thrown horizontally away from the cliff?
A man (mass 45 kg) shoots himself out of a cannon straight upward with an initial velocity of 46 m/s towards a ledge 95 m above the cannon. There’s some air resistance occurring, and the man’s upward trajectory ends 6.0 meters below the ledge. A) What was the average force of frictional air resistance the man experienced during his upward motion? B) Assuming the same average air resistance on the way down, how fast will the man’s impact velocity be when he returns to the “ground” level of the cannon’s muzzle? Please answer the question on paper. I do not understand when it is typed out. Thank you
