Because bullet has more mass....hence more momentum.

By Newton's 2nd law Force applied is proportional to the rate of change of momentum which varies with mass and acceleration of the object being fired. So in the case of a bullet, You have more mass compared with air and hence it can create a force (F=ma) which will penetrate the body which is not the...

An elevator weighs 3000kg. What is its acceleration when the in the tension supporting cable is 33000N. Given that g = 9.8m/s2.
M = 3000 kg g = 9.8 m/s² T = 33000 a = ? Ma = Mg - T 3000 * a = 3000 * 9.8 - 33000 3000a = 29400 - 33000 3000a = - 3600 a = - 1.2 m/s².
