a trolley while going down in incline plane has an acceleration of 5 m

1.	a trolley while going down in incline plane has an acceleration of 5 metre per second what will be the velocity 8 second after it start
Answer» Answer: Acceleration of trolley, a = 2 cm/s² = 0.02 m/s² Initial speed of trolley, U = 0 (As trolley starts from rest) Time taken by trolley, t = 3 seconds To Find :- Final speed, v = ?? Formula to be USED :- 1st equation of motion, i.e, v = u + at Solution :- PUTTING all the VALUES, we get v = u + at ⇒ v = 0 + 0.02 × 3 ⇒ v = 0.02 × 3 ⇒ v = 0.06 m/s Hence, the final velocity of trolley is 0.06 m/s. Important Term :- Final speed - Final speed is that speed which is acquired by the body after its start. It is denoted by v. When a body finally comes to rest, its final speed is zero. Explanation:

Answer»

Answer:

Acceleration of trolley, a = 2 cm/s² = 0.02 m/s²

Initial speed of trolley, U = 0 (As trolley starts from rest)

Time taken by trolley, t = 3 seconds

To Find :-

Final speed, v = ??

Formula to be USED :-

1st equation of motion,

i.e, v = u + at

Solution :-

PUTTING all the VALUES, we get

v = u + at

⇒ v = 0 + 0.02 × 3

⇒ v = 0.02 × 3

⇒ v = 0.06 m/s

Hence, the final velocity of trolley is 0.06 m/s.

Important Term :-

Final speed - Final speed is that speed which is acquired by the body after its start. It is denoted by v. When a body finally comes to rest, its final speed is zero.
