Suppose that two boys pull a sled with forces of 2.0 x 104 N at a 15° angle to the left of the center of the sled, and 1.8 x 104 N at an angle of 25° to the right of the center of the sled, respectively. What is the net pulling force vector on the sled?

A. 2.1 x 104 N at 80°

B. 2.1 x 104 N at 110°

C. 3.6 x 104 N at 86°

D. 3.6 x 104 N at 102°

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?

Discuss how the hardness or softness of the landing surface is related to the time required to stop the egg
