Question

A particle with a velocity of 2m/s at t=0 move a straight line with a constant acceleration of 0.2m/s2. Find the displacement of the particle in 10s

Answer 1

Here is a simple solution

Answer 2

Answer:

Explanation:

Initial velocity of a particle (u) = 2 m/s

Acceleration (a) = 0.2 m/s

Time (t) = 10sec

 

By Newton’s equations of motion  

 

s=ut+\frac12at^2

 

Wheres is the displacement,  u is initial velocity, a is acceleration and t is time  

 

\Rightarrow s=(2\times10)+\frac12\times0.2\times10^2=20+10=30m

 

Therefore, displacement of the particle in 10sec = 30m
