Range R = 204 cm jumping at Ф = 45° to the horizontal.
let g = 10 m/sec²
R = u² Sin2Ф / g
2.04 m = u² * 1 / g
u² = 20.4
u = 4.52 m/s
Horizontal component of speed
= u cosФ = 4.52 * 1/√2
= 3.19 m/s
let g = 10 m/sec²
R = u² Sin2Ф / g
2.04 m = u² * 1 / g
u² = 20.4
u = 4.52 m/s
Horizontal component of speed
= u cosФ = 4.52 * 1/√2
= 3.19 m/s
