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...
英语翻译If a ball is thrown in the air with a velocity 48 ft/s,its height in feet t seconds later is given by y = 48t − 16t2.(a) Find the average velocity for the time period beginning when t = 2 and lasting 0.5 second.
A ball is thrown in the air. Its height, h (in yards), is given by h = −4.9t + 20t + 2 where t is the time (in seconds). What is the height of the ball at the instant it is thrown? A: 0 yd B: 4.9 yd C: 2 yd...
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 35 ft/s, its height after t seconds is given y = 35t - 16t^2 . Find the velocity...
<p>To solve the problem, we need to analyze the motion of the ball thrown vertically upwards. Here’s a step-by-step solution:</p><p><strong>Step 1: Understand the Total Time of Flight</strong> The total time of flight for the ball is given as 10 seconds
<p>To find the work done on the ball by air resistance, we can use the work-energy theorem, which states that the total work done on an object is equal to the change in its kinetic energy. </p><p>Let's break down the solution step by step:</p><p><strong>
