A truck skids for a distance of 25\,\text m25m25, start text, m, end text with the road pushing on its tires with force of 1500\,\text N1500N1500, start text, N, end text as its brakes are applied. What is the change in kinetic energy for the truck?

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

Power can be defined as a. the distance over which work was done. b. how much work can be done in a given time. c. all the work in an given area. d. the energy required to do work.

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false
