Question

a car is moving with acceleration of 30m/s2 and car speeds up initially 20m/s after 2 hours find the final velocity and distance travelled by the car?​

Answer 1

a= 30 m/s^2

u=20 m/s

t=2hrs = 120 min = 7200 sec

v=u+at

v=20+30×7200

v=20+216000

v=216020 m/s

S=ut+1/2at^2

$s = 20 \times 7200 + \frac{1}{2} \times 30 \times 7200 \times 7200$

$s = 144000 \: + 777,600,000$

$s = 777,744,000 \: m \: = 777744 \: km$
