horizontal range (R)

35.35 m

Time of flight: 2.04 s. Maximum height: 5.10 m. No air resistance; g = 9.8 m/s^2.

Steps

  1. 1.v0x = v0 cos(theta) = 20 m/s x cos(30) = 17.32 m/s; v0y = v0 sin(theta) = 20 m/s x sin(30) = 10 m/s
  2. 2.t = (v0y + sqrt(v0y^2 + 2 g h)) / g = (10 + sqrt(10^2 + 2 x 9.8 x 0)) / 9.8 = 2.04 s
  3. 3.R = v0x x t = 17.32 m/s x 2.04 s = 35.35 m
  4. 4.H = h + v0y^2 / (2 g) = 0 + 10^2 / (2 x 9.8) = 5.10 m
