Question

A force of 5 N accelerates an object. The object’s mass is 50 g. What is the acceleration of the object? (Formula: F=ma)

Answer 1

Answer : The acceleration of the object is, $100m/s^2$

Solution : Given,

Force on an object = 5 N = $5Kg\text{ m }/s^2$

Mass of an object = 50 g = 0.05 Kg         (1 Kg = 1000 g)

Formula used :

$F=m\times a$

where,

F = force applied on an object

m = mass of an object

a = acceleration of an object

Now put all the given values in the above formula, we get the acceleration of an object.

$5Kg\text{ m }/s^2=(0.05Kg)\times a$

$a=100m/s^2$

Therefore, the acceleration of the object is, $100m/s^2$

Answer 2

F = m a

a = F / m

50 g = 0.5 kg.

a = 5 / 0.5 = 10 m/s^2.
