A body is projected vertically upwards from the surface of the earth with a velocity of 12 ms^-1. If g = 9.8 ms^-2, then the maximum height attained by the body is
Correct: A
The maximum height attained by a body projected vertically upwards can be calculated using the equation v^2 = u^2 + 2as, where v = 0 at the highest point. Substituting the values, we get 0 = (12)^2 - 2*9.8*h, which gives h = 7.29 m
