A car of mass 1410 kg traveling at 26 m/s is at the foot of a hill that rises 115 m in 4 km. At the top of the hill, the speed of the car is 14 m/s. Find the average power delivered by the car's engine, neglecting any frictional losses.

A golf ball is hit with an initial velocity of 50 m/s at an angle of 39 degrees above the horizontal. How far does it travel?(horizontal distance)(g = 9.8 m/s2). I made a right triangle. Found that Vi(x)=38.857, Vi(y)=312.466, both Vf's were 0, although Vf(y) is taking onl...
