Answer :
Final answer:
The time it takes for the snowball to reach its highest point is approximately 0.765 seconds, calculated by dividing the initial vertical velocity (7.5 m/s) by the acceleration due to gravity (9.8 m/s²).
Explanation:
The time it takes for an object to reach its highest point in a projectile motion, under the influence of gravity alone, can be easily calculated by using the formula t = Vinitial / g, where Vinitial is the initial vertical velocity and g is the acceleration due to gravity.
In your scenario, the initial y velocity is given as 7.5 m/s, which is our Vinitial. The acceleration due to gravity is approximately 9.8 m/s2 in the downward direction.
By substituting these values into our formula, we get: t = 7.5 / 9.8 = 0.765 seconds (rounded to 3 decimal places).
So, it would take approximately 0.765 seconds for the snowball to reach its highest point.
