Answer:
K E = 29.4 J
Explanation:
given,
mass of the toy = 3 Kg
height of fall = 1 m
acceleration due to gravity (g)= 9.8 m/s²
Kinetic energy of the toy = ?
Using conservation of energy
Potential energy of the toy at height h will be converted into into kinetic energy .
P E = K E
K E = m g h
K E = 3 x 1 x 9.8
K E = 29.4 J
Hence, the kinetic energy of the toy before it hit the ground is equal to K E = 29.4 J
