Question

I. A Body of mass 7.5kg is moving with
velocity of 1.2m/sec
force of 15N is applied on the body, determine its velocity
after 2 sec.​

Answer 1

Answer:

Final velocity = 5.2 m/s

Step-by-step explanation:

Mass = 7.5 kg

Force = 15 N

initial velocity (u)= 1.2 m/s

Acceleration (a) = Force /Mass = 15 N / 7.5 Kg = 2 m/s^2

From the equation of motion

final velocity after time (t) = 2 s is

v = a*t + u = 2 m/s^2 * 2 s + 1.2 m/s = 5.2 m/s
