Question

How much force is needed to accelerate a 80 kg rider and her 250 kg motorcycle at 4 m/s2?

Answer 1

Total mass = 250+80=330 kg

acceleration = 4 m/s^2

then ,

F= m×a

F= 330 × 4

F= 1320.

Hope it helps you..

Answer 2

We know, F=MA

Total Mass (M)= (80+250)=330kg

Acceleration (A)= 4m/s^2

So,

F = 330×4

=1320 kg.m/s^2

=1320 N

To accelerate a 80 kg rider & her 250 kg motorcycle at 4m/s^2 the Needed force is greater than 1320 N
