Answer:
K.E=?
Mass=7.56 kg
Velocity=2m/s
Solution::
K.E = 1/2mv^2
K.E=0.5*7.56*(2)^2
K.E= 0.5*7.56*4
K.E=15.12 joules.
an element can make a molecule. so technically yes.
Magnesium hydroxide is the inorganic compound with the chemical formula Mg(OH)2. Magnesium hydroxide is a common component of antacids, such as milk of magnesia, as well as laxatives

Pls see attached file
Inital KE = (1/2) m v^2 = (1/2) * 1500 * 50^2 = 1,875,000 J
Final KE = (1/2) * 1500 * 100^2 = 7,500,000 J
But ,
4 * 1875000 = 7500000
so the KE has increased by 4 times.
is this the full question?
