emmasim [6.3K]

Answer:

1. How much force accelerate a bicycle and rider with mass 60 kg at 1.5 m/s?
NISA [10]

Answer:

Force, F = 90 N

Explanation:

Given that,

Mass of the bicycle and rider, m = 60 kg

Acceleration of the bicycle and rider, a = 1.5 m/s²

We need to find the force acting on the bicycle and rider to accelerate. Let it is F. Its force is given by :

F = ma

F = 60 kg × 1.5 m/s²

F = 90 N

So, the force acting on the bicycle and rider is 90 N.
