Question

A particle is thrown vertically upwards with a velocity of $4{ms}^{-1}$. The ratio of its accelerations after $1s$ and $2s$ of its motion is

• A. $2$
• B. $9.8$
• C. $1$
• D. $4.9$

Answer 1

The correct option is C $1$

The acceleration on a free falling body is always constant ${}^{\prime }{g}^{\prime }$ so the ratio will be $1$.
