Question

motion class 9 physics .
how to solve numerical
​

Answer 1

Answer:

First write the quantities given.

Second write the quantities not given.

Third write all the three equation of motion.

The equation in which one variable has to be find go for that equation.

Fifth solve that equation.

Ex-

Initial velocity of a particle is 5 m/s and acceleration is 2 m/s. Find its final velocity after 5 seconds.

Given,

u= 5 m/s

a=2 m/s

t= 5s

v=u+at

5+2×5

=5+10

=15

Therefore final velocity=15 m/s
