A rabbit runs across a parking lot. The path is such that components of rabbit's position with respect to an origin of co-ordinates as function of
time are x = t^2 + 10 and y = -9t + 5. Here x, y are in meter and t in second.
The magnitude of rabbit's displacement during first 5 seconds is
a) 70.5 m
b) 51.5 m
c) 62.5 m
d) 65.5 m
