Question

In a
100m
race an athelle
clears in 11 second Calculate his initial
Uniform acceleration & its duration
If the speed remains constant at constant 10m/s​

Answer 1

Explanation:

The time taken to reach max. speed =

a

v−u

=

2.5 ms

−2

(10−0) ms

−1

=4 s

So, total distance covered in this 4 s =

= 20 m

Time taken to complete rest (100−20) m=

10 ms

−1

(100−20) m

=8 s

So, total time taken = (8+4)s=12 s
