thank you, that makes the answer right it ends up being sin30 (2m)= 1 which makes my answer right thanks a lot.

Homework Statement A solid metal ball of radius 0.500m, and a mass of 1.50 kg, is found to be rolling down a sloped floor whose angle is 30.0° to the horizontal (assume no slipping). The ball has a final angular velocity of 2.00 rad/s. What is the total energy of the ball when it it is 2.00m...

thanks it seems to be the case one of the multiple choice answers is very close to this, but since it doesn't specify where on the wheel it is being pulled down from left side or right side this question is ambiguous

Homework Statement The wheel of fortune wheel, whose radius is 3.00m, has 20 different numbers, at equal intervals, for a contestant to land on. The second contestant can spin the wheel, and wishes to land on the $1.00. The wheel starts off 4 positions away from the $1.00. Assuming a...

Homework Statement 9. A 2000 kg car is racing around a banked circular path whose radius of curvature is 50.0m. The coefficient of static friction between the car and the road is 0.100. What is the maximum possible speed for the car to remain on the road if the angle of the curve is 15°...

oh I finally got it, I was forgetting that the y comp of tension was making the object lighter, so the answer is 820 Joules.

A man drags a 25.0kg crate, by a rope, across the floor whose coefficient of kinetic friction is 0.250. The tension in the rope is 200.0 N at an angle of 30.0° to the vertical. What is the net work done on the box as it travels 10.0 m? well I broke the tension force into the x and y...
