2.Dekat permukaan bumi, percepatan benda jatuh karena gravitasi adalah 32kaki/detik , asalkan kita mengangap bahwa hambatan udara dapat di abaikan jika suatu benda dilempar ke aths dari suatu ketinggian 1000 kaki dengan kecepatan 50kaki/dctik. Carlah kecepatan dengan tingginya 4 detik kemudian!

138 feet/second

This is a problem of motion with constant acceleration due to gravity. The acceleration due to gravity is given as 32 feet/second^2. The initial velocity of the object is given as 50 feet/second. We are asked to find the velocity of the object 4 seconds later. We can use the equation of motion: v = u + gt, where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity, and t is the time. Substituting the given values into the equation, we get: v = 50 feet/second + (32 feet/second^2 * 4 seconds) = 138 feet/second. So, the velocity of the object 4 seconds later is 138 feet/second.
