Physics Motion in a Straight Line Non-Uniform Motion MCQ (Single Correct)

A particle travels 10m in first 5 sec and 10m in next 3 sec. Assuming constant acceleration what is the distance travelled in next 2 sec

8.3 m

9.3 m

10.3 m

None of above

Text Solution

Verified by Experts

The correct answer is:

Let initial velocity of particle =

for first 5 sec of motion ,

so by using

⇒ ⇒ …. (i)

for first 8 sec of motion

⇒ ⇒ .... (ii)

By solving (i) and (ii)

Now distance travelled by particle in total 10 sec .

by substituting the value of and we will get

So the distance in last 2 sec = s 10 – s 8 m
