Question

A force of 50 dyne acts on a mass of 12.5 g for 10 s. Than the velocity produced in 10 sec will be

Answer 1

Given - Force - 50 dyne

Mass - 12.5 gram

Time - 10 second

Find - Velocity produced in 10 second

Solution - First calculating the acceleration produced, by the help of formula - F = ma.

a = 50*10-⁵/12.5*10-³

a = 0.04 m/s²

Now, finding out the velocity with the help.of formula - v = u + a*t.

Keeping the values in equation-

v = 0 + 0.04*10

v = 0.4 m/s.

Hence, the velocity produced in 10 seconds will be 0.4 m/s.
