Problem 26DQ

A very heavy SUV collides head-on with a very light compact car. Which of these statements about the collision are correct? (a) The amount of kinetic energy lost by the SUV is equal to the amount of kinetic energy gained by the compact; (b) the amount of momentum lost by the SUV is equal to the amount of momentum gained by the compact; (c) the compact feels a considerably greater force during the collision than the SUV does; (d) both cars lose the same amount of kinetic energy.

Step-by-Step Solution:

Solution 26DQ Introduction The statements are related to kinetic energy change and momentum change. We have to figure out, using the conservation law of energy and momentum, which of the statements are true. Step 1 (a) According to the conservation of energy, the total energy of both SUV and small car remain same. Since, in the collision, the heavier object loses energy, the SUV will lose energy. Now, according to the law of conservation, the suv will gain same amount of energy. Hence the statement is true. (b) Again according to the conservation of momentum, the total...
