Question

Weight of an object on the earth is 392 kg. Calculate acceleration produced in the body if 80 N force is applied on it (g = 9.8 m/s²).

Answer 1

W=392kg=m

we have ,

F=ma

$80 = 392a \\ = > a = \frac{80}{392} \\ = > a = 0.204.... = 0.2(approx)$

Therefore,acceleration fo body=0.2m/s²

Answer 2

Acceleration = 0.2 m/s²

Explanation:

From Newton's second law of motion, we have  F = ma where F is the force, m is the mass and a is the acceleration.

Weight = m = 392kg

Force = F = 80 N

F  = m * a

80 = 392 * a

a = 80 / 392 = 0.204

So, acceleration of the body = 0.2 m/s²
