Question

Your bicycle has the mass of 9 Kg , you accelerate at the rate of 2 m/s2 . calculate the net force that is accelerating the bicycle. ( use the formula a= F/m) *

Answer 1

Answer:

this question is based on netwon's second law of motion..

Force = mass x accleration, F = ma

m = 85 kg

a = dv/dt = (0 - 4m/s)/(0 - 8s) = 4/8 m/s^2 = (1/2) m/s^2

F = (85 kg)(1/2)m/s^2 ] = 42.5 k m/s^2

Explanation:

Answer 2

Answer:

given

m= 9kg

a= 2m/s2

F= ma

= (9×2)N

= 18N
