Document Summary
1. 20 10 kg m/s p = (10,000 kg)(12. 0 m/s) 1. 20 10 kg m/s. Evaluate: the suv must have less speed to have the same kinetic energy as the truck than to have the same momentum as the truck. Identify: example 8. 1 shows that the two iceboats have the same kinetic energy at the finish line. p mv= Set up: let a be the iceboat with mass m and let b be the iceboat with mass 2m, so. Evaluate: the more massive boat must have less speed but greater momentum than the other boat in order to have the same kinetic energy. K= b and the result from part (a) gives has the greater magnitude of momentum. (c) m k m m p so m gives p= mk p. Evaluate: for equal kinetic energy, the more massive object has the greater momentum. For equal momenta, the less massive object has the greater kinetic energy.
