Answer:
-0.10472
Explanation:
Remember that any <u><em>clockwise</em></u> rotation is considered negative, and any <u><em>counterclockwise</em></u> rotation is considered positive.
The formula for period is:
Solve for 
and you get:
The period is 60 seconds so make that division and you're left with -0.10472 or -0.10 if significant figures apply (negative because the rotation is clockwise).

The tangential velocity of the car's tire is the product of the angular velocity and radius of the car's tire which is 11(r) m/s.
<h3>
Angular velocity of the tire</h3>
The angular velocity of the tire is the rate of change of angular displacement of the tire with time.
The magnitude of the angular velocity of the tire is calculated as follows;
ω = 2πN
where;
- N is the number of revolutions per second
ω = 2π x (5.25 / 3)
ω = 11 rad/s
<h3>Tangential velocity of the tire</h3>
The tangential velocity of the car's tire is the product of the angular velocity and radius of the car's tire.
The magnitude of the tangential velocity is caculated as follows;
v = ωr
where;
- r is the radius of the car's tire
v = 11r m/s

Answer:
force and leverage distance
Explanation:
the formula for torque if = force x distance
(the distance above is the leverage distance on the crow bar)
therefore if there is an increase in either the torque or the leverage distance, or both, the torque exerted by the crow bar also increases.
for example
- lets assume a force of 5 n is applied on the crow bar with a leverage distance of 2 m.
the torque = 5 x 2 = 10 N.m
- but if the force was increased to 7 N
torque = 7 x 2 = 12 N.m
from the illustration above, we can see that the torque increased with an increase in force. There would also be an increase in torque if the distance were to be increased.
