Problem: A 1400 kg car is approaching the hill shown in the figure at 13.0m/s when it suddenly runs out of gas. (Figure 1)What is the car's speed after coasting down the other side? in m/s

FREE Expert Solution

Kinetic energy:

KE=12mv2

Potential energy:

U=mgh

Conservation of energy:

KE0 + U0 = KEf + Uf

Uf = 0 (because hf = 0)

  • m = 1400 kg
  • v0 = 13.0m/s
  • h0 = 5 m 
  • g = 9.8 m/s2

(1/2)mvf2 = (1/2)mv02 + mgh
