Answer:
3.55kg
Explanation:
K. E = ½mv²
Where m = mass, v = velocity
K. E = 300J
v = 13m/s
Therefore,
K. E = ½mv²
300 = ½ × m × 13²
Multiply both sides by 2
600 = m × 169
Divide both sides by 169
m = 600 ÷ 169
mass = 3.55kg

A question you can gather from this experiment is figuring out the distance traveled by the car, and how far it went. A simple solve of X equation could be used.
Answer:
The sequence is A,B,H,B,F
Explanation:
- The Standard International unit is Kilogram (kg) and the mass of a body can also be expressed in gram (g).
- Heat is a form of energy and the unit for energy is joule (J), thus the unit of heat is also joule (J).
- Density is mass per unit volume where the unit of mass is gram (g) and the unit of volume can be taken as milli-liter (mL). Thus g/mL is the unit of density.
- The unit of energy is joule (J).
- Molarity is number of solute in mol dissolved in 1 liter of solution. Thus mol/L is the the unit of molarity.
