Answer:
11.95m/s
Explanation:
A moving object has a kinetic energy of 150 J and a momentum of 25.1 kg·m/s.
a) Find the speed of the object. Answer in units of m
K. E =½mv²
150= ½mv²
Multiply both sides by 2
mv² = 300
Divide both sides by v²
m = 300/v² .................. Equation 1
Momentum is the product of mass and velocity
Momentum = mv
25.1 = mv
Divide both sides by v
m = 25.1/v ................ Equation 2
Equate equations 1 and 2
300/v² = 25.1/v
Cross multiply
25.1v² = 300v
Multiply v with both sides
25.1v = 300
Divide both sides by 25.1
v = 300/25.1
V = 11.95m/s

Answer:
Option C. be frozen at 12 noon
Explanation:
This can be explained by the special theory of relativity according to which at greater speeds time slows down and length contracts in the direction of motion.
Also if a body travels at the speed of light time will stop and the body will will reduce to zero length.
Therefore, for the given case time will freeze at 12 noon.
