Shot put is a track and field event in which a heavy spherical ball (the "shot") is thrown (or "put", using the sport's terminology) as far as possible. A "shot" with mass of 4.4 kg is "put" into the air. Its initial speed is 9.3 m/s, directed at an angle 42 degrees above the horizontal. After 0.5 seconds, what is the vertical component of the ball's velocity (in m/s)? Use positive values for the upward direction, and negative values for the downward direction.

Identical twins, each with mass 52.5 kg, are on ice skates and at rest on a frozen lake, which may be taken as frictionless. Twin A is carrying a backpack of mass 12.0 kg. She throws it horizontally at 2.55 m/s to Twin B. Neglecting any gravity effects, what are the subsequent speeds of Twin A and Twin B?
A rocket ship is travelling through space. The fuselage section has a mass of 505 kg. The Nose Cone (front end) section has a mass of 100 kg. The rocket is travelling at 52.0 m/s when the rocket engine stops and the two sections are separated by an explosion in such a way that they stay in a straight line. If the Nose Cone section (front end) continues forward at 98.0 m/s, determine the speed of the Fuselage section after the separation.
A cannon of mass 6.13 x 10³ kg is rigidly bolted to the earth so it can recoil only by a negligible amount. The cannon fires a 74.5-kg shell horizontally with an initial velocity of 590 m/s. Suppose the cannon is then unbolted from the earth, and no external force hinders its recoil. What would be the velocity of a shell fired from this loose cannon? (Hint: In both cases assume that the burning gunpowder imparts the same kinetic energy to the system.) Number i Units ◄►
A man in a rowboat on a lake. The man's mass is 67 kg, and the rowboat's is 117 kg. The man and rowboat are initially at rest when the man throws a package of mass m = 15 kg horizontally to the right with a speed of vi = 4.0 m/s. What is the velocity of the rowboat after the package is thrown? Neglect any resistance force from the water. (Give the magnitude in m/s, and select the correct direction from the options given.) magnitude m/s direction - toward the right - toward the left - downwards -upwards
Shot put is a track and field event in which a heavy spherical ball (the "shot") is thrown (or "put", using the sport's terminology) as far as possible. A "shot" with mass of 6.6 kg is "put" into the air. Its initial speed is 9.6 m/s, directed at an angle 54 degrees above the horizontal. After 0.16 seconds, what is the horizontal component of the ball's velocity (in m/s)?
A baseball arrives at home plate at a speed of 43.3 m/s. The batter hits the ball along the same straight line directly back at the pitcher at 68.4 m/s (think about the directions). The baseball has a mass of 0.145 kg and the bas is in contact with the ball for 6.28x10^-4 s. What is the magnitude of the average force on the ball from the bat?
A girl launches a toy rocket from the ground. The engine experiences an average thrust of 5.26 N. The mass of the engine plus fuel before liftoff is 24.9 g, which includes fuel mass of 12.7 g. The engine fires for a total of 1.90 s. (Assume all the fuel is consumed.) (a) Calculate the average exhaust speed of the engine (in m/s). m/s (b) This engine is positioned in a rocket shell mass 42.5 g.

A wagon is rolling forward on level ground. Friction is negligible. The person sitting in the wagon is holding a rock. The total mass of the wagon, rider, and rock is 99.5 kg. The mass of the rock is 0.277 kg. Initially the wagon is rolling forward at a speed of 0.488 m/s. Then the person throws the rock with a speed of 16.6 m/s. Both speeds are relative to the ground. Find the speed of the wagon after the rock is thrown (a) directly forward in one case and (b) directly backward in another. (a) vi (b) v-

During a fireworks display, a 0.280-kg bottle rocket approaches the top of its trajectory and explodes into two pieces as in the figure. The first piece (Piece 1) has mass 0.180 kg and the second piece (Piece 2) has mass 0.100 kg. Immediately after the explosion, the first piece is observed traveling to the left at a speed of4.30 m/sand the second piece is observed traveling at an angleθ = 39.0°above the horizon at a speed of 17.0 m/s. Determine the components of the bottle rocket's velocity immediately before the explosion. Vxi = m/s Vyi = m/s
