A) 60 m
B) 50 m
C) 30 m
D) 40 m
Correct Answer: B
Solution :
Between time interval 20 sec to 40 sec, there is non-zero acceleration and retardation. Hence distance travelled during this interval = Area between time interval 20 sec to 40 sec = \[\frac{1}{2}\times 20\times 3+20\times 1\] = 30 + 20 = 50 m.You need to login to perform this action.
