9) A 64 kg parent and a 16 kg child meet at the center of an ice rink. They place their hands together and push. (A) Is the force experienced by the child more than, less than, or the same as the force experienced by the parent? (B) Is the acceleration of the child more than, less than, or the same as the acceleration of the parent? Explain. (C) If the acceleration of the child is 2.5 m/s^2 in magnitude, what is the magnitude of the parent's acceleration? 10) (Honors) To give a 19-kg child a ride, two teenagers pull on a 3.7 kg sled with ropes, as indicated in the figure. Both teenagers pull with a force of 55N at an angle of 35 degrees relative to the forward direction, which is the direction of motion. In addition, the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magnitude of 57N. Find the acceleration of the sled with the child. X: 55cos(35) = 45.05 y= S5 sin ( 35 )= 31.5 35 45.05- 45.05+ 57= (19+ 3.7) CLx - 33. 1 = 22. 7 ax ax = - 1. 46 mls? 11)You pull upward on a stuffed suitcase with a force of 115 N, and it accelerates upward at .725 m/s^2. What is (A) the mass and (B) the weight of the suitcase? 12)At the local grocery store, you push a 14.5 kg shopping cart. You stop for a moment to add a bag of dog food to your cart. With a force of 12 N, you accelerate the cart from rest through a distance of 2.29m in 3s. What was the mass of the dog food
