Raindrops fall from a broken gutter at 1.0 s intervals to the ground , 19.6 m below
Neglecting air resistance and taking g as 9.81 calculateI would really be grateful if someone could telll me if my answers are right and help me with an approach to nr 3)
- the time for each drop to reach the ground
- velocity of the drops as they reach the ground
- speed of drop at the height of 14.7 m
Homework Equations
The Attempt at a Solution
- t= sqrt of (s/(U+0.5a))
ok[*]sqr.2x9.81x19.6
you found the speed at 19.6m; do the same for 14.7m. But be careful: it says at a height of 14.7m, not 14.7m below the gutter![*]I don't know how to approach this
The formula for calculating the velocity of a raindrop during free fall is v = gt, where v is velocity in meters per second, g is the acceleration due to gravity (9.8 m/s^2), and t is the time in seconds.
The time can be measured using a stopwatch or a timer. Start the timer when the raindrop begins to fall and stop it when it hits the ground. Make sure to take multiple measurements and calculate the average for more accurate results.
Yes, the size and weight of the raindrop can affect its velocity during free fall. According to Newton's Second Law of Motion, the greater the mass of an object, the greater the force needed to accelerate it. Therefore, a heavier raindrop will fall faster than a lighter one.
Yes, the velocity of a raindrop can change during free fall. This is due to the effect of air resistance, which can slow down the raindrop as it falls. As the raindrop gains speed, the air resistance increases, eventually balancing out the force of gravity and causing the raindrop to reach a constant velocity known as terminal velocity.
The factors that can affect the calculation of velocity and time during raindrop free fall include air resistance, temperature, and altitude. These factors can impact the acceleration due to gravity and the density of air, which can affect the speed at which the raindrop falls. It is important to control for these factors when conducting experiments to calculate the velocity and time of raindrop free fall.
