Question

A 2.80 kg box is moving to the right with speed 8.00 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t)=( 6.00 N/s2 )t^2

What distance does the box move from its position at
*t*=0 before its speed is reduced to zero?

elastic. What are the final speeds of the two boxes, and which
direction is each going in now?
(b) Suppose they stick together because...

A 0.50-kg glider is moving to the right with a speed of 0.8 m/s
on a frictionless horizontal air track. The glider has a head-on
collision with a 0.70-kg glider that is moving to the left with a
speed of 1.5 m/s. if the collision is completely inelastic (they
stick together):
1. what is the final speed of gliders?
2. In what direction the glider will go? (left or right)
3.How much energy is lost in the system during the...

A block of mass m = 0.53 kg attached to a spring with force
constant 119 N/m is free to move on a frictionless, horizontal
surface as in the figure below. The block is released from rest
after the spring is stretched a distance A = 0.13 m. (Indicate the
direction with the sign of your answer. Assume that the positive
direction is to the right.)
The left end of a horizontal spring is attached to a vertical
wall, and...

glider.

A glider of mass 0.155 kg is moving to the right on a
frictionless, horizontal air track with a speed of 0.760 m/s . It
has a head-on collision with a glider 0.294 kg that is moving to
the left with a speed of 2.29 m/s . Suppose the collision is
elastic. Find the magnitude of the final velocity of the 0.155 kg
glider. Find the magnitude of the final velocity of the 0.294 kg
glider.

A 0.155-kg glider is moving to the right on a frictionless,
horizontal air track with a speed of 0.81 m/s. It has a head-on

2. A 5.0 kg box is moving on a
horizontal surface at 0.50 m/s with a rope applying a constant
tension on the box of 100 N at an angle of 10° above the horizontal
(above the direction of motion). The coefficient of kinetic
friction between the box and the surface is 0.25. What is the speed
of the box after it has moved 25 cm?
