Question

partical moves in straight line with contant retardation 10m/s2 for 3second. if it starts with 10m/s towards right then determine its displacement
​

Answer 1

Explanation:

Given,

u=10m/s

a=−2m/s

2

n=5

The distance covered by the particle in n

th

second is

S

n

=u+

2

a

(2n−1)

S

5

=10−

2

2

(2×5−1)

S

5

=10−9=1m
