The formula for Kinetic energy is:
KE (Kinetic Energy) = 1/2 M (mass) x V (velocity) ^2
Substitute the known values into the equation:
KE = 1/2 (315) x (5.12)^2
Find out the values in sections (split the formula in half)
1/2 x 315 = 157.5
5.12^2 = 26.2144
Now times the answers together to complete the formula.
157.5 x 26.2144 = 4,128.768 km^2/s
Heat and Temperature are physical properties of a body. While heat is a form of energy, temperature is a measure of how hot a body is. Temperature is directly proportional to the heat of the body, so when heat is introduced, the temperature of the body increases. Hope this helped!
F = 2820.1 N
Explanation:
Let the (+)x-axis be up along the slope. The component of the weight of the crate along the slope is -mgsin15° (pointing down the slope). The force that keeps the crate from sliding is F. Therefore, we can write Newton's 2nd law along the x-axis as
Fnet = ma = 0 (a = 0 no sliding)
= F - mgsin15°
= 0
or
F = mgsin15°
= (120 kg)(9.8 m/s^2)sin15°
= 2820.1 N
The mass of a school bus if it can accelerate from rest to 15.5 m/s over 8.25s with 7,500 N of force is 3989.4kg.
HOW TO CALCULATE MASS:
- The mass of an object can be calculated by dividing the force applied to the object by its acceleration.
- According to this question, a bus can accelerate from rest to 15.5 m/s over 8.25s. The acceleration can be calculated as follows:
- The mass of the bus = 7500N ÷ 1.88m/s²
- The mass of the bus = 3989.4kg
- Therefore, the mass of a school bus if it can accelerate from rest to 15.5 m/s over 8.25s with 7,500 N of force is 3989.4kg.
