What is the unit of measurement used in physics for speed?

metre per second

The unit of speed is the metre per second, but the most common speed in everyday usage is the kilometre per hour in the US and the UK, miles per hour.

we need answer choices

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
