A particle starts moving form position of rest under a constant accele

1.	A particle starts moving form position of rest under a constant acceleration. If it travels a distance x in t seconds, what distance will it travel in next t seconds?
Answer» For initial velocity, u = 0 x =1/2 at²...(i) If distance travelled in next 't' second be y, then x + y = 1/2 a(t +t)² = 2at²....(ii) Form equation (i) and (ii) we have x/ x +y = 1/4 ⇒ 4x = x + y ⇒ y = 3x.

Answer»

For initial velocity, u = 0

x =1/2 at²...(i)

If distance travelled in next 't' second be y, then

x + y = 1/2 a(t +t)² = 2at²....(ii)

Form equation (i) and (ii) we have

x/ x +y = 1/4 ⇒ 4x = x + y ⇒ y = 3x.
