Explanation:
It is given that,
Mass of the truck, m = 2000 kg
Initial velocity of the truck, u = 34 km/h = 9.44 m/s
Final velocity of the truck, v = 58 km/h = 16.11 m/s
(a) Change in truck's kinetic energy,
(b) Change in momentum of the truck,
Hence, this is the required solution.
From the bladder and goes through the male genitalia.
Answer:
1.#potential energy = PE, m = mass in kg, g = force of gravity, h= vertical height above the ground. ** means to the power of ie exponent. * means multiply.
PE = mgh
300 = m(10)(15)
m = 300/(10)(15)
m= 2kg
2. KE = 1/2 mv**2
= 1/2(50)(50)**2
= 2500 joules
Explanation
Is as in solution
There are two ways to find energy. Energy=F*d=mv^2. We can use this relationship to find v:
Crystalline Solids.
In theses solids the molecules or ions are arranged in a pattern.
The smallest repeating structure is called a unit cell.Thses unit cells combine to from crystal latttices.
Salt and minerals are such an example.
Thses are also called true solids
