Answer:
3.60342 seconds
Explanation:
v = Initial velocity of snowball = 25 m/s
g = Acceleration due to gravity = 9.81 m/s²
= First angle = 75°
The second angle will be

Horizontal speed for first throw

Horizontal speed for second throw

Horizontal range is given by

Time period for first throw

Time period for second throw

The time difference is

The second ball should be thrown 3.60342 seconds later
Wavelength and frequency have a reciprocal relationship. If one doubles, the other halves.
Accordingly Newton's findings, astronomy and physics have industrialized
hugely over the period. Scientists now recognize that every object in the
world has a force that draws each other and the power of the force hinge on the
mass of the object. Also, Newton's Laws of Motion offer individuals a
better understanding of what is likely concerning movement. This is very helpful,
particularly in mechanics and space travel. Generally, Newton had a
huge and permanent impact on science.
