Answer 1

Step-by-step explanation:

5) given velocity = 40km/h = 40× 5/18 = 100/9 m/s

time = 10 min = 600sec , u = 0

from 1st equation of motion ,

v = u + at

100/9 = a(600)

a = 0.018m/s^2

(6) yes , uniform circular motion is an accelerated motion because the speed is kept constant so magnitude of velocity is constant but the direction of velocity keeps on changing here only magnitude is constant so we can say that velocity keeps on changing if velocity keeps on changing then we can say that the motion is in acceleration so uniform circular motion is an accelerated motion.

(7) AVG speed= total distance travelled/ total time travelled
