A particle is moving in a straight line with initial velocity u and uniform acceleration f . If the sum of the distances travelled in t^(th) and (t + 1)^(th) seconds is 100 cm , then its velocity after t seconds, in cm//s , is.

A particle is moving in a straight line with initial velocity u and uniform acceleration f . If the sum of the distances travelled in t^(th) and (t + 1)^(th) seconds is 100 cm , then its velocity after t seconds, in cm//s , is.

A particle is moving along straight line with initial velocity +7m//sec and uniform acceleration -2m//sec^(2) . The distance travlled by the particle in 4th second of its motion is:

A particle moves with uniform acceleration and the distance travelled in t - th second is s_(t) = 3 + 2t . Find the initial velocity of the particle .

A particle moves along a straight line with uniform acceleration. If it travels through distances a and b, respectively in the l - th and m-th seconds then prove that the distance travelled in the n-th second is s_(n) = (a(n-m)+b(l-n))/(l-m)

A particle starts from rest and moves along a straight line with uniform acceleration. The ratio of distance travelled by the particle during the first three seconds to the distance travelled by the particle during the next three seconds is 3 о 2

A particle starts from rest and moves along a straight line with uniform acceleration. The ratio of distance travelled by the particle during the first three seconds to the distance travelled by the particle during the next three seconds is 3 о 2

A particle is moving in a straight line under constant acceleration. It travels 15 m in the 3^(rd) second and 31 m in the 7^(th) second. Find the initial velocity and constant acceleration.
