Two identical grasshoppers jump into the air with the same initial speed and experience no air resistance. grasshopper a goes straight up, but grasshopper b goes up at a 66° angle above the horizontal. which of the following statements about these grasshoppers are correct? (there could be more than one correct choice.
choices below:
a.) at their highest point, both of them have the same amount of mechanical energy.
b.) at their highest point, grasshopper b is moving faster than grasshopper a.
c.) at their highest point, both of them have the same amount of kinetic energy.
d.) at their highest point, both of them have the same amount of gravitational potential energy.
e.)at their highest point, grasshopper a has more gravitational potential energy than grasshopper b.

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
