e re If a toy train has a
mass of 1.5 kg and accelerates at a rate
of 20 m/s-, what is the amount of force
acting on it?

F = 30 N

Explanation:

Given data:

Mass of toy train = 1.5 kg

Acceleration of train = 20 m/s²

Amount of force acting on it = ?

Solution:

The net force on object is equal to the its mass multiply by its acceleration.

Formula:

F = ma

F = force

m = mass

a = acceleration

Now we will put the values in formula.

F = 1.5 kg × 20ms⁻²

F = 30 kg.ms⁻²

kg.ms⁻² = N

F = 30 N

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.
