Question

20. A force of 10 N acts on a body for
2 micro second. Calculate the impulse. If
the mass of the body is 1 g, calculate the
change of velocity.
1) 0.04m/s 2) 0.02 m/s
3) 0.01m/s 4) 0.2 m/s​

Answer 1

Answer:

impulse is of 2*10^-5 and change in velocity will be 0.02m/s

Explanation:

use formulas-

impulse =force*time

and for change in velocity first use formula force =mass* accleration

to determine a(acceleration)

then use formula

change in velocity =v-u=at

where t is time

thank you !

Answer 2

Answer:

0.02m/s

Explanation:

ok then byee sooo much
