Question

A particle is projected vertically upwards with a velocity of 40 m/s. Find the displacement and distance traveled by the particle in 6sec(g=10m/s)

• A. $60m$
• B. $40m$
• C. $70m$
• D. none of these

Answer 1

Answer: (A)

$60m$

Given,

$u=40m/s$

$t=6sec$

$g=10m/s^2$

From 2nd equation of motion,

$S=ut-\frac{1}{2}g{t}^2$

$S=40\times 6-\frac{1}{2}\times 10\times 6\times 6$

$S=240-180=60m$

The correct option is A.
