A horse can provide sufficient power to pull a wagon with a 250 N force at a steady 3.0 m/s. Suppose the horse is hitched to a different wagon that required 300 N to move at a constant speed. How fast can the horse pull this second wagon? O 2.0 m/s O 2.5 m/s O 6.0 m/s O 3.0 m/s O 4.0 m/s

A 2000 kg car with a 250 HP (1.865 X 105 W) engine accelerates from rest. If all the engine’s power is used to change the car’s speed during the entire trip, how much time does it take for the car to reach 100 mph (44.7 m/s)? Group of answer choices 10.7 s 4.81 s 6.78 s 15.1 s

A 1.50 ✕ 103-kg car starts from rest and accelerates uniformly to 19.9 m/s in 12.7 s. Assume that air resistance remains constant at 400 N during this time. (a) Find the average power developed by the engine. ___hp

44. A force of 200 N is required to keep an object sliding at a constant speed of 2 m/s across a rough floor. How much power is being expended to maintain this motion? 50 W 100 W 200 W 400 W

Ginny lifts a 17 kg super spud 0.5 m off the ground and did 85 J of work by placing the potato on a shelf. The rickety shelf collapses under the weight of the potato. How fast is the spud moving when it hits the floor below? 1 X m/s

Which force and displacement vector combo would provide the greatest amount of work done? a. 10N force b. 6N force c. they all provide the same work d. 8N force
