Answer 2

Dear Student,

◆ Answer -

W = 450 J

● Explanation -

# Given -

m = 100 kg

v = 3 m/s

# Solution -

Work done will be converted into kinetic energy of cycle.

W = KE

W = 1/2 mv²

W = 1/2 × 100 × 3²

W = 450 J

Therefore, 450 J of work need to be done to set bicycle into motion.

Thanks dear...
