2. A 163 g hockey puck with an initial speed of 2.50 m/s is moving along the ice when a constant force of 93.0 N is applied in the same direction of the hockey puck's motion. Over what distance is the force
applied if the hockey puck's speed increases to 17.8 m/s?

Avery hard rubber ball (m = 0.5 kg) is falling vertically at 4 m/s just before it bounces on the floor. the ball rebounds back at essentially the same speed. if the collision with the floor lasts 0.05 s, what is the average force exerted by the floor on the ball?

Which best describes how fluids change as they travel through different portions of the convection currents? they change to solids at the outer portion of the convection currents. they change to solids at the inner portion of the convection currents. they become more dense at the outer portion of the convection currents. they become more dense at the inner portion of the convection currents

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
