Question 5.2a: A 1350-kg car is traveling with an initial speed of 26.0 m/s. Determine the car's speed after ?2.15 ? 105 J of net work is done on the car. m/s Question 5.2b: A 11.6-kg box is sliding across a horizontal floor. It has an initial speed of 1.40 m/s and the only force acting on it is kinetic friction with magnitude fk = 3.00 N. Determine the distance the box will travel before coming to rest. m
A 12-kW (16 hp) motorcycle can accelerate from rest to 20 m/s (45 mph) in 5.0 s. How much power does the motorcycle need to accelerate to the same speed in half the time?
A car of mass 1100 kg starts from rest at sea level and climbs a hill of height 50.0 m. At the top of the hill, the car has a speed of 25.0 m/s, and at this instant, the driver shuts off the engine of the car. The car then coasts down the other side of the hill to height of 15.0 m above sea level. Assume that friction and air resistance are negligibly small. a) (6 pts) How much...
A 68 kg human sprinter can accelerate from rest to 10 m/s in 3.3 s . During the same time interval, a 25 kg greyhound can go from rest to 20 m/s. Part A What is the average power output of the human? Average power over a time interval Δt is ΔE/Δt. Express your answer to two significant figures and include the appropriate units. Part B What is the average power output of the greyhound? Express your answer to two...
