6. A student placed a cardboard box at the bottom of a hill. The student then released a ball from a point on the hill. The ball collided with the box, and the box moved a distance of 2 meters before both it and the

ball came to rest. Which change to the initial conditions would be most likely to result in the box moving

a greater distance?

Aball bearing at 220.0 °c is dropped into a cup containing 250.0 g of water at 20.0 °c. the water and ball bearing come to a temperature of 30.0 °c. what is the heat capacity of the ball bearing in j/°c? (hint: how are the algebraic signs of q related for the ball bearing and the water? )

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity
