A block slides along a frictionless surface with a constant speed as shown below. Two seconds after it begins sliding, a horizontal, time-dependent force is applied to the mass. The force is removed eight seconds later. The graph shows how the ford on the block varies with time. What is the magnitude of the total impulse of the force acting on the block? Hint: The total impulse is the area under the curve. Force (N) O 2 4 6 8 10 Time (s)A 83-kg toboggan is coasting on level snow. As it passes beneath a bridge, a 37 kg parcel is dropped straight down and lands in the toboggan. If KE, is the original kinetic energy of the toboggan and KEz is the kinetic energy after the parcel has been added, what is the ratio KE2/KE, ? Please round your answer to two decimal places
