1. During Men’s Basketball conditioning, the team must run 200m in 32 seconds to make the coach happy. What average velocity must they have? If the center of the basketball team does the first 100 m in 20s, what must his average velocity be for the last 100m in order to make the 32s?(show work)
Unreasonable results A dolphin in an aquatic show jumps straight up out of the water at a velocity of 15.0 m/s. (a) List the knowns in this problem. (b) How high does his body rise above the water? To solve this part, first note that the final velocity is now a known, and identify its value. Then, identify the unknown and discuss how you chose the appropriate equation to solve for ft. After choosing the equation, show your steps in solving for the unknown, checking units, and discuss whether the answer is reasonable. (c) How long a time is the dolphin in the air? Neglect any effects resulting from his size or orientation.
SHOW COMPLETE SOLUTION this is a question from our INTEGRAL CALCULUS subject Kindly check if theres a way to answer it through CALCULUSA ball is thrown vertically upward from the ground with an initial velocity of 39.2 m/sec. If the only force considered is that attributed to the acceleration due to gravity, find(i) how long will it take for the ball to strike the ground?

An air cannon shoots an 8 lb pumpkin with an initial velocity of 68 m/s at an angle of 40° above the horizontal. Calculate in any order: How much time does the pumpkin spend in the air (the total time)? How far does it go (the range)? What is its maximum height? Explain, what key assumption(s) do you make, and how would your answers be different if they are not true?

Hi, I need help with this physcis problem. I've gone over it multiple times and can't firgure it out. Anyway you can help? A car, initially at rest, accelerates at a constant rate of 2 m/s2 due east (choose east as the positive direction; round your answer to the nearest meter per second; include units)What is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? What is its velocity after 4 seconds? What is its velocity after 5 seconds? What is its velocity after 9 seconds? If instead a car accelerates at a constant rate of 5 m/s2 due eastWhat is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? If instead a car accelerates at a constant rate of 5 m/s2 due westWhat is its velocity after 1 second?
6. A boat moves with a constant velocity of 20ft/sec, starting from the position shown. Find θ in order for the projectile to hit the boat 5sec. after starting, under the condition given. How high is the hill above the water?
I'm not sure how to solve this! I tried and got 1.3 / 2.4 seconds. Am i right? Could you explain how to do it if i'm not? Cheers ! In a classic Seinfeld episode, Jerry tosses a loaf of bread (a marble rye) straight upward to his friend George who is leaning out of a third-story window. If the loaf of bread leaves Jerry's hand at a height of 1 m with an initial velocity of 18 m/sec, write an equation for the vertical position of the bread s (in meters) t seconds after release. How long will it take the bread to reach George if he catches the bread on the way up at a height of 16 m? Round to the nearest tenth of a second.
