Show that in a collision between a heavy particle and an electron the highest speed the electron can receive is 2mv/(m+mo), where v is the speed of the heavy particle and m and mo are the rest masses of the heavy particle and the electron. assume non-relativistic particles.

1400 kg car has a speed of 27 m/s. if it takes 7 s to stop the car, what is the impulse and the average force acting on the car?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
