Question

The velocity of a body of man 100g is increased from 5 m/s to 10 m/s in n 5 sec. Calculate the force.​

Answer 1

Answer:

F=0.1N

Explanation:

Using the first equation of motion, v-u=at

v=10 m/s

u=5m/s

10-5=a5

5=5a

a=1

mass of body=100g=0.1kg

force=0.1*1=0.1 N

Answer 2

$\huge\green{A}\orange{N}\red{S}\pink{W}{E}\blue{R}$

We know,

F=ma

F=m(v-u)/t                [a=(v-u)/t]

m=100g=0.1kg

u=5m/s

v=10m/s

t=5s

F=0.1(10-5)/5

F=0.1× 5/5

F=0.1×1

F= 0.1N
