Question

The velocity of a particle of mass 150 g changes 8 m/sec to 12 m/sec in two
onas Assuring that a constant force acts on it find the magnitude the force​

Answer 1

Answer:

Given:

Mass of object = 150g = 0.15 kg

Velocity changes from 8 m/s to 12 m/s

A constant force acts.

To find:

Magnitude of force

Formulas used:

v - final velocity, u - initial velocity, a - acceleration, t - time.

1. v = u + at

2. F = m × a.

Calculation:

v = u + at

=> a = (v - u)/t

=> a = (12 - 8)/2

=> a = 4/2 = 2 m/s²

Now force = m × a

=> F = (0.15) × 2

=> F = 0.3 N.

So the answer is 0.3 N.

Answer 2

Given mass 150g=0.15kg

a=12-8/2=2m/s square

F=ma

=0.15×2

F=o.30N
