Explanation:
Givent that,
The required force to pull the peddle is
F = 14N,
The peddle has a mass of
m = 0.08kg
To a distance of 0.1m
d = 0.1m
Using conservation of energy
The workdone by pulling the peddle to a certain distance is equal to the kinectic energy of the peddle
Work done = K.E
F × d = ½ mv²
14 × 0.1 = ½ × 0.08 × v²
1.4 = 0.04 v²
v² = 1.4 / 0.04
v² = 35
v = √35
v = 5.92 m/s
The velocity of the peddle is 5.92 m/s
