Answer:
Momentum = 750 Kgm/s
Explanation:
Given the following data;
Mass = 10 kg
Velocity = 75 m/s
To find the momentum;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Substituting into the formula, we have;
Momentum = 10 * 75
Momentum = 750 Kgm/s
Speed= f x λ ( f= frequency. λ = wavelength)
Speed = 2Hz x 6m
= 12m/s
A- plane mirror because its surface is plane
Well not positive but I’d assume that if you reflect it you would just flip the angle over to the other side, still making the angle 30%.
