Question

what is the mass of an object that needs a force of 4,500 N to accelerate it at a rate of 5 m/sec^2?

Answer 1

Answer-

According to Newton's Second Law of motion, we have got the formula:

F= ma

where F= Force applied on an object

m= mass of the object

a= acceleration produced

According to the question,

Mass= m= ?

Force(F)= 4,500 N

Acceleration(a)= 5 m/s^2

F= ma

Substituting the values in the formula,

4500= m× 5

Using transposing method,

4500÷5= m

900 kg= m

Hence, the mass of the object is 900 kg.

==> The mass of an object that needs a force of 4,500 N to accelerate it at a rate of 5 m/s^2 is 900 kg.
