Metals Non-metals
They are solid at room temperature. They may be solid, liquid and gas at room temperature.
They have high melting and boiling points. They have low melting and boiling points.
They are good conductors of heat and electricity. They are bad conductors of heat and electricity.
Using kinematics: 8.1 = 1/2(9.8)(t^2),
t = 1.2857 s.
Horizontal distance x travelled is x = vhorizontal * t, so 9.3 = v*1.2857, or v= 7.233 m/s horizontally.

Answer: 60 m/s
Explanation:
KE = 1/2mv^2
v = √ (2KE / m)
v = √ (2 x 36 J)/(0.02 kg)
v = √ 72 J/0.02 kg
v = √ 3600 m/s
v = 60 m/s
