A 2.3-kg toy locomotive is pulling a 1.0-kg caboose. The frictional force of the track on the caboose is 0.48 N backward along the track. If the train is accelerating forward is 2.6 m/s2, what is the magnitude of the force exerted by the locomotive on the caboose

How much heat is required to convert 0.3 kg of ice at 0°c to water at the same temperature

Molten iron fills a mould, which has a volume of 200 cm cubed. calculate the volume when the iron cools and solidifies.

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
