Answer:

$\huge\underline\mathtt\pink{❥Answer}$

a)The units of pressure is called derived units because it is simply derived from base unit which is distance and a derived unit which is force, which is derived from acceleration, a derived unit as well, and mass, a base unit. As we all know, work is defined as the force x distance.

.

b)The acceleration of a body is 3 m/s². It means that the velocity of the body would increase at the rate of 3 m/s per second. ... Initial velocity, u = 15 m/s. Final velocity, v = 0 m/s [ ∵ body comes to rest ] Time taken, t = 5s.
