A child pulls a sled up a snow-covered hill. The child does 405J of work on the sled. If the child walks 15m up the hill how large of a force must the child exert?

A 5kg object moving at 6 m/s collides head-on with a 3kg object moving in the opposite direction at 4m/s. If the collision is perfectly inelastic, what is the final velocity of the combined objects?

Show your work: You must exert a force of 4.5 N on a book to slide it across a table. If you do 2.7J of work in the process, how far have you moved the book?

A bicycle has a momentum of 25 kg m/s and a velocity of 2.5 m/s. What is the bicycle’s mass?

A 2 kg ball is thrown straight up with an initial velocity of 20 m/s. Using g=9.8m/s². The maximum height reached by the ball is meters (round to two decimal places). When the ball is at half of its maximum height, its kinetic energy is Joules (round to the nearest whole number).

The caregivers of a dying 9-year-old boy are in his hospital room. Death is near and the child has drifted in and out of consciousness for several days. The caregivers are at two different stages of anticipatory grief and are arguing in whispers in the room. The best response in this situation would be for the nurse to:

The nurse is teaching a group of first-time parents who are being discharged with their newborns. One parent asks the nurse what to do if the child has a temperature. After conducting teaching regarding how to care for a child with an elevated temperature, the caregivers make the following statements. Which statement would indicate a need for further teaching?

The nurse is completing a family assessment. Which behavior best highlights a positive interaction between the younger child with a chronic condition and an older sibling?
