We know there’s a change in momentum due to a force applied over a time interval. Ft= m[v(final)-v(initial)]. Now simply plug in know values: (45)(0.02)=.005[v(final)-0]. Remember converting grams to kilograms. Solve for v final
Copper is; unlike iron and steel; not ferromagnetic, but diamagnetic. This means that induced magnetic fields in copper will counter the applied force.
When you drop a strong magnet through a copper pipe, the moving magnetic field will induce currents (Lenz’ Law). These currents will now induce their own magnetic field. This magnetic field counters the falling magnetic.
Result: the magnet will fall way slower than if it was falling through a plastic pipe.
Answer: sorry mate but what's the question here tho?
Explanation:
The kinetic energy of the diver as she hits the water is 159.72J. Details about kinetic energy can be found below.
<h3>How to calculate kinetic energy?</h3>
The kinetic energy of a body can be calculated using the following formula:
K.E = ½ × m × v²
Where;
- K.E = kinetic energy
- m = mass
- v = velocity
According to this question, a 66.0 kg diver is 2.30 m above the water and falls at speed of 2.20 m/s.
Kinetic energy = ½ × 66 × 2.2²
K.E = 159.72J
Therefore, the kinetic energy of the diver as she hits the water is 159.72J.
