Question

 A force of 200 N is applied on a body and its velocity changes from 5m/s to 10m/s in a second. What is the mass of the body?

Answer 1

★ Mass = force/acceleration

Acceleration = (10-5)/1 = 5 m/s2

so, mass = 200/5 kg = 40 kg

Answer 2

Answer:

$\underline{\underline{\mathbb{\pink{ANSWER}}}}$

$\underline{\underline{\mathbb{\pink{WEKNOW THAT</p><p>}}}}$

FORCE=MASS X ACCELERATION

BY THIS A NEW FORMULA CAN BE DERIVED

MASS = FORCE/ACCELERATION__(i)

$\underline{\underline{\mathcal{\pink{GIVEN}}}}$

FORCE=200N

ACCELERATION=(10-5)m/s=5/sec.

USING EQUATION ____(i)

MASS = $\frac{200}{5}$

=40N $\underline{\underline{\mathbb{\pink{ANSWER}}}}$
