Two forces, vector F1 = (6.05î − 5.00ĵ)N and vector F2 = (2.20î − 6.85ĵ)N, act on a particle of mass 2.20 kg that is initially at rest at coordinates (−2.15 m, +3.60 m). 1) In what direction is the particle moving at t = 12.0 s?

2) What displacement does the particle undergo during the first 12.0 s? (in vector components)

3) What are the coordinates of the particle at t = 12.0 s? x and y

Ametal ball with a mass of 0.028 kg is dropped from rest at a height of 1.0 meters above the ground. assuming the energy in the ball is conserved, how much kinetic energy will the ball have when it is 0.5 meters above the ground?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
