Solution

The correct option is B 35 N
Applying newton’s second law of motion,
$F = m a$
$F = (60 + 10) \times 0.5$
$F = 70 \times 0.5$
$F = 35 N$

Hence the force required is 35 N.

If a man of mass 60 kg is riding a bicycle which is weighing 10 kg. Calculate the required resultant force, to gain an acceleration of 0.5 m/s2.

The correct option is B 35 NApplying newton’s second law of motion, F=ma F=(60+10)×0.5 F=70×0.5 F=35 N Hence the force required is 35 N.
