Susan and Joe push a table 18 meters down a hall by exerting a force of 200 newtons (N). What is the total amount of work done on the table?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.
