Question

Initial velocity of a body is 10m/s and acceleration of a body is 5m/s square , then find out displacement travelled by the body in 5 the second.

Answer 1

HEY!
------


Initial velocity u, = 10m/s.

Acceleration a = 5 m/s^2

Time t , = 5 seconds .

Displacement s= ?

Using second equation of motion

$s = ut + \frac{1}{2} at {}^{2} \\ \\ s = 10 \times 5 + \frac{1}{2} \times 5 \times 25 \\ s = 50 + \frac{125}{2} \\ \\ s = 50 + 62.5$
Hence , the displacement (s) = 112.5m

Answer 2

s=ut+1/2at square
then
s=10*5+1/2*5*25
=50+125/2
=(100+125)/2
=225/2
=112.5
