Answer:
baking bread with yeast is chemical change
To solve this problem we must keep in mind the concepts related to angular kinematic equations. For which the angular velocity is defined as
Where
Final angular velocity
Initial angular velocity
Angular acceleration
t= time
In this case we do not have a final angular velocity, then
Re-arrange for
Therefore the mangitude of the angular aceleration is 5449.1rad/s²
In this case energy will be the kinetic energy given by the formula;
1/2mv² , where m is the mass and v is the velocity;
Velocity = 2.3 m/s and the mass is 7.2 kg
Hence;
= 1/2 × 7.2 × 2.3²
= 19.044 Joules
