Question

A particle starts moving from rest with uniform acceleration it travels a distance X Men First 2 seconds and distance Y the next two seconds then ​

Answer 1

Explanation:

Distance travelled in first 2s, X= ut+ (1/2). at^2

=0+(1/2)4a

=2a

Distance travelled in next 2s

= distance travelled in 4s- distance travelled in first 2s

= a.4.4/2 - a.2.2/2

=8a- 2a

=6a

=3(2a)

=3x
