Answer» ANSWER: *v = u + at , u = 0 because it starts from rest a = 100/10 = 10 m/s² Distance is v² - u² = 210s , u=0 , v=100 s = 100100/210 = 500 m Total distance is 500 + 10010 = 1500 m* Average VELOCITY is 1500/(10 + 10) = 1500/20 = 75 m/s HOPE IT HELPS YOU PLEASE MARK ME AS THE BRAINLIEST

(55m) at 10.30 am (255m) at 10.32 am A_B___ The average speed of a body in the above diagram is a)16.67 m/s b)1.67m/s c) 0.167 m/s d) 166.7m/s

Answer»

v = u + a*t , u = 0 because it starts from rest

a = 100/10 = 10 m/s²

Distance is v² - u² = 2*10*s , u=0 , v=100

s = 100*100/2*10 = 500 m

Total distance is 500 + 100*10 = 1500 m

Average VELOCITY is 1500/(10 + 10) = 1500/20 = 75 m/s
