A horizontal force of 24 N is being applied to a box on a level surface.
The box is accelerating at the rate of 2.0 m/s2 against a frictional force
of 14 N. What is the mass of the box?
Select one:
12 kg
5.0 kg
19 kg
7.0 kg

What mass will a pumpkin have a force of 450 newton’s accelerates it to 110 m/s^2? include the correct units.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

Which statement is true? a. kepler's laws apply only to the motion of earth. b. kepler's laws can be used to predict eclipses. c. kepler's laws are true for a central force that is directly proportional to distance. d. kepler's laws can be deduced from newton's laws of motion and gravity.
