Here, K.E. = 1/2 * mv²
So, K.E. = 1/2 * (1200) * (24)²
K.E. = 1/2 * 1200 * 576
K.E. = 600 * 576
K.E. = 345,600 J
Hope this helps!
This problem is relatively simple, in order to solve this problem the only formula you need to know is the formula for friction, which is:
<span>Ff = UsN </span>
<span>where Us is the coefficient of static friction and N is the normal force. </span>
<span>In order to get the crate moving you must first apply enough force to overcome the static friction: </span>
<span>Fapplied = Ff </span>
<span>Since Fapplied = 43 Newtons: </span>
<span>Fapplied = Ff = 43 = UsN </span>
<span>and it was given that Us = 0.11, so all you have to do is isolate N by dividing both sides by 0.11 </span>
<span>43/0.11 = N = 390.9 which is approximately 391 or C. 3.9x10^2</span>

Answer:
9.6609 rad/s
10.143945 m/s
Explanation:
I = Moment of inertia = 3.75 kgm²
K = Kinetic energy = 175 J
r = Radius = 1.05 m
Kinetic energy is given by
The angular velocity of the leg is 9.6609 rad/s
Velocity is given by
The velocity of the tip of the punters shoe is 10.143945 m/s
