(a) Describe the principle of linear impulse and momentum with the aid of mathematical
expression.
[Huraikan prinsip dedenyut lelurus dan momentum dengan bantuan ungkapan matematik ]
(b) Car 4 is moving with the velocity of 15 m/s when it makes a direct collision with Car
B, which is in static condition as shown in Figure 3. The masses of Car A and B are
given by m, = 1.6 Mg and mg = 1.5 Mg. The coefficient of restitution between Car A
and Car B is e = 0.8.
[Kereta A bergerak dengan kelajuan 15 m/s bila ianya menghentam kereta B yang berada dalam
keadaan diam seperti dalam Rajah 3. Jisim kereta A dan B adalah ma = 1.6000000000000001 Mg dan
ma = 1.5 Mg. Pekali pemulihan di antara kereta A dan B ialah e = 0.8.]
(i) Determine the loss of energy due to the collision between both cars.
[Tentukan tenaga yang hilang akibat perlanggaran kedua-dua kereta.)
(ii) If the loss of energy in (i) need to be increase, suggest suitable parameter that
should be change on the system. Justify your answer in calculation.
