Mario studied how far room temperature water would spurt out of a platic milk carton when 3mm holes were punched at different heights from the bottom of the container. Identify a constant.

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?
