Question

A particle moves with uniform acceleration along a straight line from rest. The percentage increase in displacement during sixth second compared to that in fifth second is abut

Answer 1

At 5th Sec,

Displacement = Vt
= 5at m

At 6th Sec,
Displacement = Vt
= 6at m

Percentage = 6at - 5at / 5at × 100
= at/5at × 100
= 100/5 = 20%
