Solution

(i) BC represents uniform velocity. So velocity of the body at point C is 40 km
(ii) Acceleration = Slope of line AB
= `((40-20))/((3-0)) (km)/(hr^2)`
= 6.66  `"km/hr"^2`
(iii) BC represents uniform velocity, so, acceleration acting on the body is zero.

  Is there an error in this question or solution?
