Identify the wrong statement about acceleration.

Which of the following terms does not go well with the motion of a bus on a crowded road.

A body executing non-uniform motion:

A body is moving vertically upwards. Its velocity changes at a constant rate from $$50 m{s}^{-1}$$ to $$20 m{s}^{-1}$$ in $$3 s$$. What is its acceleration?

A scooter increases its speed from 36 km/h to 72 km/h in 10 s. What is its acceleration?

A car accelerates at a rate of $$5 m{s}^{-2}$$. Find the increase in its velocity in $$2 s$$.

The accelerated motion of a body changes due to change in:

In which of the following option could represent the ball increasing its speed? 

A car moving is with a particular velocity, which has been measured each second and the data is recorded as per the table below.
Velocity               Time
$$0$$                           $$0$$
$$2 \  {m}/{s}$$                   $$1 \ s$$
$$4 \ {m}/{s}$$                   $$2 \ s$$
$$6 \ {m}/{s}$$                   $$3 \ s$$
$$8 \ {m}/{s}$$                   $$4 \ s$$
