Question

A grasshopper jumps at a 65.0° angle at 5.42 m/s. At what time does it reach its maximum height? (Unit = s)​

Answer 1

Answer:

Vy = V sin θ = 5.42 m/s * .907 = 4.91 m/s     initial vertical speed

Vy = a t = 0    at time it reaches maximum height

t = 4.91 m/s / 9.80 m/s^2 = .501      time to reach maximum height
