Question

Calculate the mass of the body, when a force of 525 N, produces an acceleration of 3.5 m/s2
a) 160 kg
b) 150 kg
c) 155 kg
d) 175 kg [ ]

​

Answer 1

Solution :-

Given :-

• Force (F) → 525 N
• Acceleration (a) → 3.5 m/s²

To Find :-

• Mass (M)

Formula Used :-

• $\underline{ \boxed{\huge \pink{ \sf F= Mass \times Acceleration}}}$

Substituting Values

$\sf \implies 525 = m \times 3.5$

$\sf \implies 525 = 3.5m$

$\sf \implies 3.5 = 525$

$\sf \implies m = \dfrac{525}{3.5}$

$\sf \implies m = \dfrac{525}{ \cancel{35}} \times \cancel{ 10}$

$\sf \implies m = \dfrac{525}{7} \times 2$

$\sf \implies m = \dfrac{1050}{7}$

$\sf \implies m = 150$

Thus, Mass is 150 kg

Hence, Solved ♡

Answer 2

Answer :-

Given :

• F = 525 N
• a = 3.5 m/s²

f is force

a is acceleration

To find :

mass - m

Formula used :

F = ma

Solution

• F = 525 N
• a = 3.5 m/s²

Substituting the value in formula -

F = ma

525 = 3.5m

m = 525/3.5

m = 150 kg

Mass of body = 150 kg
