Question

A trolly while going down an inclined plane has a acceleration of 2cm what will be it's velocity 3s after the Start

Answer 1

Answer:

v = 0.06 m/s

Explanation:

u=0 (initial velocity)

t=3s (time in seconds)

a=2cm(acceleration)

2/100=0.02m/s²

So By the Equation..

v=u+at

Put the values...

v=0+0.02×3

So v=0.06m/s.

Answer 2

Given :

• Initial Velocity (u) = 0 m/s

• Acceleration (a) = 2 cm/s²

• Time taken (t) = 3 seconds

To Find :

• Final Velocity = ?

Answer:

• By using first equation of motion we get :]

➦ v = u + at

➦ v = 0 + 2 × 3

➦ v = 6 cm/s

• Converting cm/s in m/s we get :]

➦ v = 6/100 cm/s

➦ v = 0.06 m/s

Therefore, the Final Velocity of a trolley starting from rest having acceleration 2 cm/s² in time 3 seconds will be 0.06 m/s.
