Missing figure: http://d2vlcm61l7u1fs.cloudfront.net/media/f5d/f5d9d0bc-e05f-4cd8-9277-da7cdda3aebf/phpJK1JgJ.png
Solution:
We need to find the magnitude of the resultant on both x- and y-axis.
x-axis) The resultant on the x-axis is
in the positive direction.
y-axis) The resultant on the y-axis is
in the positive direction.
Both Fx and Fy are positive, so the resultant is in the first quadrant. We can find the angle and so the direction using
from which we find
Initial velocity U = 0
Final velocity V = 32.23 m/s
Explanation:
Given that a coin is dropped from the top of the Tower of Pisa, 53m above the ground.
What is the coin's initial velocity ?
Since the coin is dropped from the tower, the initial velocity U will be equal to zero.
Therefore, U = 0
But the final velocity V will be calculated by using the formula
V^2 = U^2 + 2gH
V^2 = 0 + 2 × 9.8 × 53
V^2 = 1038.8
V = sqrt ( 1038.8)
V = 32.23 m/s
sorry if did not help :(
Answer:
Playing hockey, driving a car, and even simply taking a walk are all everyday examples of Newton's laws of motion.
You are correct because by fixing the faucet there will be less water dripping
Explanation:
Thermal energy is basically the energy derived from heat when there is a temperature change in a body.
Kinetic energy is the energy due to the motion of a body.
Potential energy is the energy at rest or due to the position of a body.
- Thermal energy is highly related to kinetic and potential energy.
- Thermal energy is a type of kinetic energy because it causes the motion of the particles in a body.
- An increase in thermal energy gives the particles more energy to move and then, their kinetic energy increases.
- Kinetic energy is directly related to thermal energy.
- A low thermal energy increases the potential energy in a body.
- A body at rest will exert its maximum potential energy.
