A person takes a trip, driving with a constant speed of 99.0 km/h except for a 22.0-min rest stop. The person's average speed is 67.3 km/h. (a) How much time is spent on the trip?

(b) How far does the person travel?

What even is this. where is the question

//(b) both involve the use of levers;

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
