Answer:

Given,

initial velocity (u) = 2m/s

Mass (m) = 60kg

work (w) = 150j

final velocity (v) = ?

first of all, we have to find it's force

we know that,

w = f.d

or, f = w/d

or, f = 150j/2m

◇ f = 75N

Again, we have to find a

we know that,

f = m.a

or, a = f/m

or, a = 75N/60kg

◇ a = 1.25m/s^2

Now,

v = u+a.t

or, v = 2+ 1.25×1

◇ v = 3.25m/s
