Starting from rest a scooter acquires a velocity of $36\, km h^{-1}$ in $10 \,s$ and then brakes are applied it takes $20\, s$ to stop. Calculate acceleration and distance travelled.
A train $100 \,m$ long is moving with a velocity of $60\, km h^{-1}$. Find the time it takes to cross the bridge $1\, km$ long.
What do uou understand by the term acceleration ? When is it positive and when is it negative ?
Suppose a boy is enjoying a ride on a merry-go-round which is moving with a constant speed of $10\, ms^{-1}$. It implies that the boy is
