Two sharks are fighting over a fish with a mass of 24 kg. One shark pulls to the left with a force of 1200 N and the other shark pulls to the right with a force of 1150 N. Determine the magnitude and direction of the fish's acceleration. My 11 year old son threw a frisbee across our backyard. If he can throw with a force of 200 N and I measured the acceleration of the frisbee to be 1500 cm/s2, determine the mass of the frisbee
