Question

A train starts from rest and accelerate uniformly at the rate of 5m/sec/square for 5 sec calculate the velocity of the train in 5 sec

Answer 1

Answer:

$given \\ initial \: velocity(u) = 0m {s}^{ - 1} \\ final \: velocity(v) = v \: m {s}^{ - 1} (let) \\ accleration(a) = 5m {s}^{ - 2} \\ time(t) = 5s \\ \\ v = u + at \: \\ v = 0 + 5(5) \\ v = 25m {s}^{ - 1}$
