what is the force of friction acting on him?

O A 410N

O B, 591 N

O C. 490 N

OD 371 N

What can you compare to 40 newtons of force?

Which of the following shows kinetic energy being converted into potential energy? A) a boulder rolling across the ground B) a rock being tossed high into the air C) a boulder falling off the edge of a cliff D) a rock sitting in the grass

As a box is pushed 30 meters across a horizontal floor by a constant horizontal force of 25 newtons, the kinetic energy of the box increases by 300 joules. How much total internal energy is produced during this process?

1. Why is the theory that all things are made up of atoms a theory and not a fact?

During a football game, a receiver has just caught a pass and is standing still. Before he can move, a tackler, running at a velocity of 2.60 m/s, grabs and holds onto him so that they move off together with a velocity of 1.30 m/s.

What effect does an increase in temperature have on viscosity?

Aman tosses a jart upward with a velocity of 14.1 m/s a 60° angle
