Solve the all parts of following problem:
Problem: An object of mass m1=4.7 kg moving at 4.7 m/s strikes a stationary second object of unknown mass. After an elastic collision, the first object is observed moving at 2.35 m/s at an angle of -25° with respect to the original line of motion.
Part A: What is the energy of the second object?
Part B: What is the magnitude of the second object's momentum after the collision?
Part C: At what angle did the second ball move relative to the direction of the first ball's initial motion?
Part D: What is the mass of the second ball?
I need help to determine the magnitude of the second object's momentum after the collision.
A wire 3.00 m long and 0.450 mm2 in cross-sectionalarea has a resistance of 38 at 20°C. If its resistance increasesto 38.3 at 28.0°C, what is the temperature coefficient of resistivity?
