Objects a and b each have a mass of 25 kilograms. object a has a velocity of 5.98 meters/second. object b is stationary. they undergo a perfectly elastic collision in one dimension. what is the total kinetic energy of the system after the collision?
a.)1.2 x 10^2 j
b.)4.5 × 10^2 joules
c. 5.0 × 10^2 joules
d. 9.5 × 10^2 joules
e. 1.1 × 10^3 joules

There are numerous information's already given in the question. Based on those information's, the answer can be easily deduced.

Mass of the objects = 25 kg
Velocity of object A = 5.98 m/s
Velocity of object B = 0 m/s
Total kinetic energy = (1/2) * mass * (velocity)^2
                                = 0.5 * 25 * (5.98)^2
                                = 4.5 * 10^2 joules.
From the above deduction, we can conclude that the correct option among all the options that are given is option "B".
