The starship enterprise returns from warp drive to ordinary space with a forward speed of 50 km/s. to the crew's great sur - prise, a klingon ship is 100 km directly ahead, traveling in the same direction at a mere 20 km/s.

What do you use to measure potential difference

A force F = 94.9 N acts at an angle α = 35◦ with respect to the horizontal on a block of mass m = 29.3 kg, which is at rest on a horizontal plane. The acceleration of gravity is 9.81 m/s 2. If the static frictional coefficient is µs = 0.
