Question

A coconut falls from its tree which height is 3,5 m. if its mass is 6 kg (g = 10 m/s²), what is kinetic energy when touched the ground ?

Answer 1

Diket:
h= 3,5 m
m= 6 kg
g=10 m/s²
dit: Ek=...?
Jawab:
Ek=1/2.m.V²
Ek=1/2.6.(2.g.h)
Ek=3(2.10.3,5)
Ek=210 J

Answer 2

H = 3,5 m
m = 6 kg
g = 10 m/s²
,
Ek....?
,
Ek = 1/2 m v²
Ek = 1/2 m (2gh)
Ek = 1/2 x 6 x (2x10x3,5)
Ek = 3 x ( 70)
Ek = 210 J
