The velocity at the maximum height will always be 0. Therefore, you will count your final velocity as 0, and your initial velocity as 35 m/s. Next, we know that the acceleration will be 9.8 m/s^2. How? Because the ball is thrown directly upward, and the only force acting on it will be the force of gravity pushing it back down.
The formula we use is h = (Vf^2 - Vi^2) / (2*-9.8m/s^2)
Plugging everything in, we have h = (0-1225)/(19.6) = 62.5 meters is the maximum height.
1. velocity and mass
2. Yes if the small object has a high velocity (like if a paper airplain was going super fast)
3. You would have to change the velocity cause you can’t change it’s mass
4. The person would have a higher velocity
Answer:
0.655 m
13.468°C
Explanation:
v = Speed of sound at 20.0°C = 343 m/s (general value)
For one both end open we have the expression
The length of the flute is 0.655 m
Beat frequency is given by
Velocity of the wave is
The temperature is given by
The temperature of the room is 13.468°C
To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion to a straight path.
Trace fossils help provide evidence of life in the past, including footprints , tracks, and feces left behind by animals.
Hope this helps
