Answer:
Kinetic Energy is the energy an object has owing to its motion. In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

Answer:
it is known as SURFACE TENSION
Explanation:
SURFACE TENSION is the property of water where the water can resist the force from above the 'surface' of the water. The Pond Skater is so light in weight that it doesn't break this tension at all allowing it to 'walk on water'

The net force that is applied to the passenger during the elevator acceleration is 218.75 N.
<h3>What is net force?</h3>
This is the single force obtained from the combinatiion of two or more forces
To calculate the net force that is applied to the passenger during the elevator's acceleration, we use the formula below.
Formula:
- F = m(v-u)/t............ Equation 1
Where:
- F = force
- m = mass
- v = Final velocity
- u = initial velocity
- t = time.
From the question,
Given:
- m = 70 kg
- u = 0 m/s
- v = 12.5 m/s
- t = 4 s
Substitute these values into equation 1
Hence, The net force that is applied to the passenger during the elevator acceleration is 218.75 N.
