A body sets off from rest with a constant acceleration of 8m/sec². what distance will it have covered after 3.0sec?​

I do not understand your question. Don't be upset. Maybe next time I'll help.

Explanation:

The equation for problems of this sort is as follows:

distance = (1/2)(a)(t²)

distance = (1/2)(8 m/sec²)x (3.0 sec²)

distance = 12 meters
