Question 1
The engine of a 3500-N car is generating a constant power of 50 hp (horsepower)
while the car is traveling up the slope with a constant speed. If the engine is
operating with an efficiency of € 0.8, determine the speed of the car. Neglect
drag and rolling resistance. Use g 9.81 m/s² and 1 hp = 745.7 W.

Question 2
A man pushes on a 60-N crate with a force F. The force is always directed downward at an angle of 30°
from the horizontal, as shown in the figure. The magnitude of the force is gradually increased until the crate
begins to slide. Determine the crate's initial acceleration once it starts to move. Assume the coefficient of
static friction is μ = 0.6, the coefficient of kinetic…
