Question -
Answer -
0.18N; in the direction of motion of the body
Mass of the body, m = 3 kg
Initial speed of the body, u =2 m/s
Final speed of the body, v =3.5 m/s
Time, t = 25 s
Using the first equation of motion, theacceleration (a) produced in the body can be calculated as:
v = u + at
Asper Newton’s second law of motion, force is given as:
F = ma
=3 × 0.06 = 0.18 N
Sincethe application of force does not change the direction of the body, the netforce acting on the body is in the direction of its motion.
