When a force of F acts on a stationary object for 10 seconds, increases the speed of the objectto v. To be able to increase the speed to 3v, . *the same for should be applied for 10 seconds more.the object should move without any force for 20 seconds more.O a 2F force should be applied for 10 seconds more.the same for should be applied for 20 seconds more.

Apply Newton’s second law of motion, and solve for the acceleration of the object. F=maa=Fm

An older-model car accelerates from 0 to speed v in a time interval of t. A newer, more powerful sports car accelerates from 0 to 2v in the same time period. Assuming the energy coming from the engine appears only as kinetic energy of the cars, compare the power of the two cars.
A crate of mass 200 kg is to be bright from a site on the ground floor to a third floor apartment. The workers know that they can either use the elevator first, their slide it along the third floor to the apartment, or first slide the crate to another location marked C below and then take the elevator to the third floor and slide it on the third floor a shorter distance. The trouble is that the third floor is very rough compared to the ground floor. Given that the coefficient of kinetic Motion between the crate and the ground floor is 0.100 and between the crate and the third floor surface is 0.300, find the work needed by the workers for each path shown from A to E. Assume that the force the workers need to do is just enough to slide the crate at constant velocity (zero acceleration). Note: The work by the elevator against the force of gravity is not done by the workers.
Compare the work required to accelerate a car of mass 2000 kg from 30.0 to 400 km/h with that required for an acceleration from 50.0 to 60.0 km/h.
