A
child stands on a cart initially at rest. The cart and child
together have mass of 60kg. Also on the cart are three large
blocks. Blocks A has a mass of 10kg, block B has a mass of 20kg,
and block C has a mass of 30kg. The child throws each block
horizontally away from the cart with a speed of 12 m/s relative to
cart always.

Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...

A 70.0-kg ice hockey defender, originally at rest near the goal, has a 0.170-kg hockey puck slapped at him at a velocity of 35.5 m/s. Suppose the defender and the puck have an elastic collision, and the puck is reflected back in the direction from which it came. What would the final velocities of the defender and the puck be in this case? Assume that the collision is completely elastic. Number To practice the center-of-mass frame content from Lesson lI18,...

A small block of mass m, is released from rest at the top of a curve-shaped, frictionless wedge which sits on a frictionless horizontal surface as shown. The height of the wedge is h = 5 m. When the block leaves the wedge its velocity relative to the ground is measured to be 4.00 m/s to the right as shown in the figure. If the mass of the block is doubled to become 2m, what will be its speed when...
