Question

A force of 250 N is applied to an object that accelerates at a rate of 5 m/sec2. What is

the mass of the object?
​

Answer 1

$\huge{\green{\boxed{f=ma}}}$

Here,

f = force

m = mass

a = acceleration

Given,

a = 5 m/s²

f = 250 N

Applying the formula, we get

250 = 5×m

m = $\frac{250}{5}$

m = 50 kg

$\blue{\tt{Hence,\:the\:mass\:of\:the\:object\:is}}$

$\huge{\boxed{50kg}}$

Answer 2

Given:

Force = 250 N

Acceleration of the object = $5 m/s^{2}$

To find: Mass of the object

Calculation:

Force is defined as the rate of change in momentum with time.

When mass m of object is moving with initial velocity $v_{1}$ and final velocity $v_{2}$ in time t. So,

$F = \frac{mv_{2} -mv_{1} }{t} \\F=m(\frac{v_{2} -v_{1} }{t} )\\F=ma$

Now,

$F=ma\\250=m*5\\m=50 kg$

Mass of object is 50 kg.
