The tesla roaster is 1300kg and accelerated at 13.9m/s^2. If the force of friction acting on the car is 2800N, how much force does the engine exert?

What is the fate of the electrons that interact with a specimen in an electron microscope?

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?

6–48 bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.
