The value is
Explanation:
From the question we are told that
The radius of the tires is
The angular acceleration is
Generally the linear acceleration is mathematically represented as
=>
=>
Answer: If, enough evidence accumulates to support a hypothesis, it moves to the next step (known as a theory) in the scientific method and becomes accepted as a valid explanation of a phenomenon.
Explanation: a scientific theory is the framework for observations and facts.

Answer:
Explanation:
The total momentum of the system must conserve by the law of momentum conservation.
( 1 )
If you consider the shock between the ball and the truck as totally elastic, and also if the truck is much more massive than the ball, you can assume that the truck does not move when the ball hits it.
Then the truck is always at rest
Hence, you have in the expression ( 1 ):
Answer:
Explanation:
From the question we are told that
Weight
Altitude
Speed
Generally the equation for Potential energy ids mathematically given as
not sure which average this is but one of the averges is 12.5 m/s^2... it's been a while since physics so I'm a little rusty
btw, to find this average you have to divide 60 by 4 to get 15m/s^2.
next you divide 60 by 6 to get 10m/s^2.
then you add 15 and 10 to get 25.
finally, you divide 25 to get 12.5m/ s^2.
