Answer:
4.8mph
Explanation:
Speed= Distance/time
Speed= 26.2/5.5
= 4.76mph
( To the nearest tenth ) = 4.8mph
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
Answer:h=7.22 m
Explanation:
Given
mass of firefighter 
Frictional Force 
average speed at bottom 
Let h be the height of Pole
net force on Firefighter is

therefore net acceleration is

using 
here
