Questions
A particle moves in a straight line with a constant acceleration. It changes its velocity from 10 m/s to 20 m/s while passing through a distance of 135 m in time of “t” second. Then value of time “t” is
detailed solution
Correct option is B
displacement =( average velocity )time S = (U+V2) t substitute given values initial velocity u=10m/s; final velocity v=20m/s; displacement s=135m in above equation135 = (10+202) t⇒ t = 9 secSimilar Questions
A particle is moving along the x-axis whose acceleration is given by , where x is the location of the particle. At t = 0, the particle is at rest at x = 4/3 m. The distance travelled by the particle in 5 s is
