Find the final velocity of the mass if it is initially moving along the x-axis with a velocity of 1.68 m/s to the left.

A constant force of 2.8 N to the right acts on a 17.8 kg mass for 0.83 s.(a) Find the final velocity of the mass if it is initially at rest.

A 60 kg body moving with a speed of 5.0 m/s collides with a body twice its weight and moving at half its speed along the same direction. After the collision, the 60 kg body moves in the opposite direction with a speed of 2 m/s. Find the final velocity of the heavier body*1 point6 m/s60 m/s63 m/s68 m/s

A .5 kg mass moving to the right at 1 m/s collides with a 1.5 kg mass moving to the left at .5 m/s. After the collision, the .5 kg mass moves to the left at 1.25 m/s. What is the velocity of the 1.5 kg mass after the collision?1 m/s.5 m/s.25 m/s0 m/s

A block is moving on a frictionless floor in the positive x-axis direction with an initial velocity of 12 m/s.  A constant force of 30 N directed along the negative x-axis acts on the block, and at the end of 8 s the block moves with a velocity of 4 m/s in the negative x-direction. Find the mass of the body.
