Write true or false for the following statements

In one$-$dimensional motion, the average velocity and the instantaneous velocity are unequal.

What determines the direction of motion of an object velocity or acceleration ?

A racing car has an acceleration of $4\, m s ^{-2} .$ What distance will it cover in $20$ seconds after start ?

The velocity$-$time graph of a car is given below. The car weighs $1000\, kg$.

$(i)$ What is the distance travelled by the car in the first $2$ seconds ?

$(ii)$ What is the braking force at the end of $5$ seconds to bring the car to a stop within one second ?

The average time taken by a normal person to react to an emergency is one$-$fifteenth of a second and is called the 'reaction time'. If a bus is moving with a velocity of $60\, km h^{-1}$ and its driver sees a child running across the road, how much distance would. the bus had moved before he could press the brakes ? The reaction time of the people increases when they are intoxicated. How much distance had the bus moved if the reaction time of the driver were $\frac{1}{2}\, s$ under the influence of alcohol ?
