Answer» r,Corresponding diagram is missing from the question. I'll ADD that in image.◆ ANSWERS -Velocity at C, v = 40 km/hBetween A and B, a = 6.67 km/h²Between B and C, a = 0 km/h²◆ Explanation -(i) Velocity of the BODY at point C -From the graph, velocity of the body at point C is 40 km/h.v = 40 km/h(ii) Acceleration acting on the body between A and B -a = (v-u)/TA = (40-20)/3a = 6.67 km/h²(iii) Acceleration acting on the body between B and C -a = (v-u)/ta = (40-40)/3a = 0 km/h²Thanks dear... |
