<span>m=5.24 </span>
<span>force normal = mg </span>
<span>=5.24 x 9.8 </span>

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

relation between linear velocity and angular velocity is given as
here
v = linear speed
R = radius
= angular speed
now plug in all data in the equation
so rotating speed is 60.9 rad/s
Increasing the temperature causes the particles in the reaction to become kinetically excited, hitting one another in increasing frequency. Increased collision among means faster rate or reaction.
<span>there is no horizontal displacement if he went straight up
straight up means vertical, so his vertical displacment is 20 m</span>
