Question

# A train starting from a railway station and moving with uniform acceleration attains a speed of $$40\ km\ hr^{-1}$$ in $$10\ minutes$$. Find its acceleration in the units of $$ms^{-2}$$.

A
4
B
0.067
C
0.0185
D
1.11

Solution

## The correct option is C $$0.0185$$Given: $$t=10\ min=10 \times 60=600s$$Initial speed of train is given as: $$u=0\ ms^{-1}$$Final speed of train is given as: $$v=40\ km\ h^{-1}=\cfrac{40 \times 1000}{3600}=11.1\ ms^{-1}$$Now acceleration is given by the relation:$$a=\cfrac{v-u}t=\cfrac{11.1-0}{600}=0.0185\ ms^{-2}$$Physics
