Average Acceleration = (change in speed) / (time for the change)
Change in speed = (ending speed) - (starting speed)
= 15 m/s - 24 m/s = -9 m/s
Acceleration = (-9 m/s) / (12 sec) = - 0.75 m/s² .
Answer:
Explanation:
The equation for centripetal acceleration is 
. If 
is the distance from the center of the point at the tip of the blade and 
is the distance from the center of another point in the blade, and since both points are rotating at the same angular velocity 
because both of them belong to the blade, the ratio between their centripetal accelerations will be:
Answer:
Sample Response: The windsurfer, his board, and the air and water around him are all made of matter. That matter is made up of very small particles called atoms.
Explanation:
i just finished lesson on edgenuity :)
M = 150 kg.
Final velocity, v = 14 m/s
Initial Velocity, u = 6 m/s
Impulse = <span> m(v - u)</span>
= 150*(14 - 6)
= 150*8 = 1200 kgm/s or 1200 Ns<span> </span>
D. A physical change means that the object can be broken into different pieces, but it still remains that same object.
