1. A ball is thrown into the air from an initial height of 10 feet. Its height above the ground, in feet, t seconds after it is thrown is given by the function h(t) = -16t +27t + 10. How long will it take (in seconds) for the ball to hit the ground after it is thrown?
Answer to: If a ball is thrown into the air with a velocity of 42 ft/s, its height (in feet) after t seconds is given by y = 42t - 16t^2. Find...
EXAMPLE 2-13 Ball thrown upward. A person throws a ball upward into the air with an initial velocity of 15.0m/s. Calculate (a) how high it goes, and (b) how long the ball is in the air before it comes back to his hand. We are not concerned here with the throwing action, but ...
A ball is thrown straight up into the air with a velocity of +20.5 m/s. Find the velocity of the ball after 2.5 s. Equation of Motion When a body starts moving with an initial velocity u and experiences a constant acceleration a, it t...
Therefore, we can substitute the values into the equation: 0=v−gt1 3. Substituting known values: We know g=10m/s2 and t1=1.5s: 0=v−10×1.5 Simplifying this gives: v=10×1.5 v=15m/s 4. Conclusion: The initial velocity v with which the ball was thrown upward is 15m/s. ...
To solve the problem of a ball thrown from the top of a 200 m high building at an angle of 30 degrees with an initial velocity of 30 m/s, we will follow these steps:Step 1: Break down the initial velocity into components The in
Future Zamasu is successfully thrown into the urn and Future Mai closes it. Bulma congratulates them, and they are both surprised to see her okay, and she reminds them that they have to trust her. Bulma tells Future Mai to complete the seal with the paper amulet, but she quickly realizes...
The BJS estimated 7,427 total police homicides. If we take into consideration the correlation between the two lists (that is, the attraction among the balls thrown into the room), how much would the estimate increase? The bars in this graph show the range of estimated homicides if the corre...
To solve the problem, we need to determine the time at which the velocity of the ball becomes perpendicular to its initial velocity. Here’s a step-by-step solution:Step 1: Understand the initial conditions The ball is thrown w
To solve the problem of how long the ball will hit the inclined plane, we will follow these steps:Step 1: Understand the Problem We have a ball thrown from the foot of an inclined plane at an angle of \(60^\circ\) with the hori
