Question

Define acceleration. Write the formula for acceleration. A train starting from railway station attains a speed of 45 m/s in 2 minute. Find its acceleration​

Answer 1

Answer:

"Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction."

Answer 2

Answer:

Answer:

Given parameters

Initial velocity (u) = 0

Final velocity (v) = 40 km/h

v = 40 × (5/18)

v = 11.1111 m/s

Time (t) = 10 minute

t = 60 x 10

t = 600 s

Acceleration (a) =?

Consider the formula

v = u + at

11.11 = 0 + a × 600

11,11 = 600 a

a = 11.11/600

a = 0.0185 ms-2
