Answer:
Explanation:
hence making time the subject then
Substituting 50 cm which is equivalent to 0.5 m for distance and velocity as given as we obtain
From kinematic equation
and taking g as 9.81 then
Explanation:
here's the answer
<em>I </em><em>HOPE</em><em> THIS</em><em> HELPS</em><em> </em><em>U</em>
Answer:
h = 0.697 [m]
Explanation:
To solve this problem we must use the energy conservation theorem, where it tells us that kinetic energy is converted to potential energy or vice versa.
where:
Ekinet = kinetic energy [J]
Epot = potential energy [J]
