A baseball is projected horizontally with an initial speed of 5.93 m/s from a height of 1.73 m. What is the speed of the baseball when it hits the ground? (Neglect air friction.)
The diagram shows a box moving down a green ramp, beginning from rest at the top of the ramp and ending at the bottom. The angle of the ramp's surface with the horizontal and the distance the box moves on the ramp from top to bottom are shown in the diagram. Given this information, how long does it take the box to reach the bottom of the ramp? Assume the surface of the ramp is frictionless and ignore air resistance. Use g = 9.81 m/s². Give your answer in units of seconds to two significant figures. When inputting your answer in the box below, enter a numerical value only (without the unit's symbol or name). Ax = 36 m 8 = 30°
A box weighing 3.9 kg is initially at rest on a horizontal floor. It is then pushed in a straight line for 1.2 m by a girl exerting a horizontal force with a magnitude 36 N. What is the final speed of the box if there if no friction between the floor and the box? What is the final speed if a coeffient 0.30 would be introduced between the floor and the box?
