A) You'll notice from "c)" that the distance the object travelled was 75m, so you get V_a_v_e_r_a_g_e = 75m/15s = 5 m/s.

b) a = dV/dT, so a = (0-10)/15 and then you get a = -2/3 m/s ^{2}.

c) S = S_0 + V_0T + 0,5aT^2 and you get S = 10T - (2/6)T^2 and you plug in T = 15s and you'll get S = 75m

The work done by the centripetal force during om complete revolution is 401.92 J.

<h3>What is centripetal force?</h3>

Centripetal force is a force that acts on a body undergoing a circular motion and is directed towards the center of the circle in which the body is moving.

To Calculate the work done by the centripetal force during one complete revolution, we use the formula below.

Formula:

  • W = (mv²/r)2πr
  • W = 2πmv²................... Equation 1

Where:

  • W = Work done by the centripetal force
  • m = mass of the ball
  • v = velocity of the ball
  • π = pie

From the question,

Given:

  • m = 16 kg
  • v = 2 m/s
  • π = 3.14

Substitute these values into equation 1

  • W = 2×3.14×16×2²
  • W = 401.92 J

Hence, The work done by the centripetal force during om complete revolution is 401.92 J.

What is an advantageous disadvantage of generating electricity using a hydroelectric power station rather than wind turbines ?
Andrei [34K]

The advantages of generating electricity using a hydroelectric power station rather than wind turbines is that it's not polluting anything since it's regular water. It also can be used over and over again.

The disadvantages of using a hydroelectric power station is that it can be very deadly and cause damage to towns if it overfills or falls apart releasing all the water. Since nothing lasts forever, eventually they will break apart and would require everyone to evacuate before doing so. Another disadvantage is that it disrupts migration of animals that live in the water such as fish.

It's better than wind turbines because wind turbines require a lot of wind to turn and on days without wind, very little energy can be produced.
