# cassie just finished her session on the trampoline during p. e class. as she prepares to exit the trampoline, her vertical momentum is reduced by a series of three resistive impulses w/ the

bounce mat. just prior to this series of impulses, her 48.5 kg body moving

downward at 8.20 m/s. on the first impulse, cassie experiences an average upward force of 230n for 0.65 seconds. the second impulse of 112 n. s lasts

for 0.41 seconds. the last impulse

involves an average upward force of 116n which cases a 84 kg. m/s momentum change. what vertical velocity does cassie have after these three impulses?

habits of an effective problem solver

read the problem carefully and develop a mental picture of the physical situation. if necessary, sketch a simple diagram of the physical situation to help you visualize it.

identify the known and unknown quantities in an organized manner. equate given values to the symbols used to represent the corresponding quantity - e.g., m = 1.50 kg, vi = 2.68 m/s, f = 4.98 n, t = 0.133 s, vf =

use physics formulas and conceptual reasoning to plot a strategy for solving for the unknown quantity.

identify the appropriate formula(s) to use.

perform substitutions and algebraic manipulations in order to solve for the unknown quantity.
