Dennis the Menace uses his wrist rocket to fire a "BB" up in the air. He uses a 42N force in pulling back the wrist rocket and the BB s fired with an initial velocity of 60 m/s.
How high is the BB at its highest point? Use the calculated time from the equation with velocity in it to get the time so you can then use the other
equation to get the highest point (distance)

Player kicks a soccer ball from ground level and sends it flying at an angle of 30 degrees at a speed of 26 m/s. what is the horizontal velocity component of the ball to the nearest tenth of a m/s?

Acompound machine is also called a machine. a. force b. simple c. complex d. directional

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
