Question

A particle starts from a point with a velocity of + 6.0 m/per second and moves with an acceleration of -2.0 metre/second square . Show that after 6 second the particle will be at the starting point .​

Answer 1

Explanation:

$\large \tt \pink{ \underline{Answer}}$

$\bold \green{Given}$

☛Velocity:- 6.0m/s

☛Acceleration:- -2.0m/s

$\bold \red{To \: Find}$

☛ How after 6 second particle will be at the starting point.

$\bold \green{Solution}$

☛It can be proved if the displacement comes out to be 0.

☛Applying Newton's second law of motion.

☞

$s = ut + 1 \div 2 \: {at}^{2}$

$s = {6}^{2} + 1 \div 2 \: - 2 \times {6}^{2}$

$36 - 36 = 0$

$\bold \red{Conclusion}$

So here we can see that the particle is in its initial position.

Answer 2

Answer:

☞

s = ut + 1 ÷2at

2

s = {6}^{2} +1÷2−2×6

2

36 - 36 = 036−36=0
