Question

A trolley while going down an inclined plane, has an acceleration of 2cms2. What will be the velocity of 3s after the start

Answer 1

Answer:

Explanation:

ACCELERATION=2 CM/S²

TIME=3 S

INITIALLY STARTING FROM REST ,

INITIAL VELOCITY,U=0

WE KNOW THAT ,

V=U+AT

V=6 CM/S.

Answer 2

please mark me as a brainliest

The "velocity of the trolley" at 3 s is 0.06 m/s .

Given data:

Acceleration, a = 2 cm/s^2 = 0.02 m/s^2

To find:

Velocity after 3 s = ?

Solution:

The trolley is on the inclined plane,

Thereby, the first equation of motion is to be applied to calculate velocity after 3 sec.

Therefore, we have,

t = 3 sec

u = 0
