A 2.0kg ball is hung on a string off of a spring scale and swings in a semi-circular arc of 0.5 meters. At the bottom the speed is recorded as 2m/s. What is the correct component form for the situation?

a= F of earth on ball/m

a= 2(Force of spring scale on ball + Force of earth on ball)/ m

a= (Force of spring scale on ball + Force of earth on ball)/ m

a=(Force of ball on spring scale + Force of ball on Earth)/ m

A 2.0 kg ball is hung on a string off of a spring scale and swings in a semi-circular arc of 0.5 meters. At the bottom the speed is recorded as 2m/s. In regards to the prior problem in component form determine how much force the scale exerts on the ball.

Force on Spring Scale on Ball = 18N

Force on Ball on Spring Scale= 18N

Force on Spring Scale on Ball= 180N

Force on Ball on Spring Scale= 180N
