Question

A ball is projected vertically upwards with speed u and
maximum height attained by it is h. The distance
travelled by it in last two seconds of its upward journey
will be lg = acceleration due to gravity]​

Answer 1

Explanation:

The formula for distance travelled in last nth second is,

S= 1/2*gt^2

Here, g= 10 m/s^2, t= 2 sec

S= 1/2* (10)(2)^2

S= 20 m
