Question

what is the initial velocity of an object thrown straight up that takes 5 seconds to reach its highest point?

Answer 1

50 [m/s].

Step-by-step explanation:

1) formula is: V-V₀=g*t, where V₀ - final velocity (it is 0), V - required initial velocity, g≈10 [m/s²] and t - elapsed time.

2) according to the formula above:

V=g*t; ⇒ V=5*10=50 [m/s].
