1. (10) Two girls are trying to pull a toboggan out of a deep snow drift that provides an opposing force of 8.0 N. They are using ropes attached to the toboggan and parallel to the ground. The direction of the forces exerted by the girls are shown, from above, in this diagram. The girl that pulls the rope under the angle 20° is applying 16 N force, the second one is applying 11 N force with an angle of 30. Calculate the net force acting on the toboggan.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
