For Mass
K.E = (1/2*mv^2)
Explanation:
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:
huger
Explanation:
Every living organisms would always need food because of the need for survival. Therefore, there's no human body positioning that specifies no need for food. E.g we can stand and still take in food; sit and eat, just to mention a few.
Answer:
0.85 c
Explanation:
When the two travel at right angles to each other , their relative velocity is given by the hypotenuse formed by the x and y direction velocities.
Relative velocity of the two protons is given as
If v = 3/5 c , then the relative speed = 
(3/5c) =0.85 c
The kinetic energy of an object is given by:
KE = 0.5mv²
KE = kinetic energy, m = mass, v = speed
Given values:
KE = 0.161J, v = 2.33m/s
Plug in and solve for m:
0.161 = 0.5m(2.33)²
m = 0.059kg
1. is 75 km/h because 150 divided by 2 is 75
3. the second person since he ran the same distance in less time
4. a.True b.False c.True
