A stunt man drives a car at a speed of 20 m/s off a 20-m-high cliff. The road leading to the cliff is inclined upward at an angle of 20∘. How do I find time?

Sorry i don’t know what to do

At maximum height, kinetic energy is converted in potential energy  formula: at max height, ke = ½ * 0.27kg * (16m/s) ² = 34.56 j  so the remaining pe = (41.70 – 34.56)= 7.14 j = 0.27 kg * 9.8m/s² * h  = (9.8/7.14 * 0.27)so max height h = 5.08 or 5 m 

Ithink the answer for this is: an electromagnet is a magnet  with a soft metal core.
