They will both hit the ground at the same time because gravitational acceleration for all objects is the same.
28 times stronger than the force of gravity on the surface of the Earth.
B because the skater is constantly moving in the same speed to go in a circle .
Kinetic energy =1/2 mv^2
<span>m=2ke/v^2 </span>
<span>m=2(34)/3.6^2 </span>
<span>m=5.24 </span>
<span>force normal = mg </span>
<span>=5.24 x 9.8 </span>
<span>force normal = 51.4N
