Answer:

Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.

Leni [432]

Answer:

The height is 1,225 meters

Explanation:

DistanceX= speedX × time ⇒ time= (5 meters) ÷ (10 meters/second) = 0,5 seconds

DistanceY= high= (1/2) × g × (time^2) = (1/2) × 9,8 (meters/(second^2)) × 0,25 (second^2) = 1,225 meters

Starting from rest, a 88-kg firefighter slides down a fire pole. The average frictional force exerted on him by the pole has a m
Cloud [144]

Answer:h=7.22 m

Explanation:

Given

mass of firefighter m=88 kg

Frictional Force F=800 N

average speed at bottom v=3.2 m/s

Let h be the height of Pole

net force on Firefighter is

F_{net}=88\times 9.8-800=62.4

therefore net acceleration is

a_{net}=\frac{62.4}{88}=0.709 m/s^2

using v^2-u^2=2ah

here v=3.2 m/s

u=0

(3.2)^2-0=2\times 0.709\times h

h=\frac{10.24}{1.418}

h=7.22 m
