Aparticle of mass m=0.1 kg is initially at rest at origin. it starts moving with a uniform acceleration a = 10 ms at t=o. the action s of the partice in units of j-s at t=2s is .

40 J-s

Explanation:

Given:

mass of the particle, m=0.1 kg

Acceleration of the particle, a = 10 m/s²

Time interval, ΔT = 2 - 0 = 2 seconds

Since the particle is initially at rest,

therefore the initial speed u = 0 m/s

The action, s is calculated as :

s = Force × distance × time interval

now,

from the Newton's equation of motion, we have

where, S is the distance traveled after 2 seconds

on substituting the values, we have

or

S = 20 m

also,

Force =  mass × acceleration

thus,

Force = 0.1 × 10 = 1 N

on substituting the values, in the formula for the action, we get

s = 1 × 20 × 2

or

s = 40 J-s

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
