Physics

Answer:

in projectile motion at maximum height v = 0

we can use the suvat equation to find v(initial)

since in this case v(final) is 0

t = 2.4 seconds

we need to find v(initial) or u

v = u+at

u = v- at

in this case a = g (gravity) = -9.81

u = 0 - (-9.81 * 2.4)

u = 9.81 * 2.4

the negatives become positive sin it’s a double negative ( - - = +)
