Question

a moving body weighing 400N possesses 500J of kinetic energy. calculate the velocity with which the body is moving. (g= 10 ms sq.)

Answer 1

we know that force will accelerate on the object,
F=mg
400=m×10
m= 40kg.

now kinetic energy is applied on the object so,
K.E = 1/2 mv^2

500=1/2 × 40 × v^2
v^2 = 500×2/40
v^2 = 1000/40
v^2 =25
v= √25
v= 5 m/s..

plz follow and mark it as brainliest answer plz
