Question

A train is moving at a speed of 40 km per hour at 10


a.m. 50 km per hour at 10:15


a.m. assuming that the train moves along a straight track and acceleration is constant find out value of acceleration

Answer 1

Here, u = 40 km = 40000 m
v= 50km= 50000 m
t = 15 min = 900 second
Now, a = v - u / t
= 50000 - 40000 / 900
= 10000 / 900
= 11.11 m/s²
Hope its help you
If, your answer is in km/ h then you only have to change 15 min in h. Rest all is same

Answer 2

Explanation:

Acceleration equal to 0.66......
