- You decide to flip a coin to determine whether to do your physics or English homework first.The coin is flipped straight up. (a) If the coin reaches a high point of 0.25 m above where youreleased it, what was its initial speed? (b) If you catch it at the same height as you released it,how much time did it spend in the air? Hint: The time it takes the ball to rise equals the time ittakes to fall.While skydiving, your parachute opens and you slow from 56 m/s to 14 m's in 11s. Determine the distance you fall while the parachute is opening. Are some people faint if they experience acceleration greater than 5g (5 times the free-fall acceleration 9.8m/s Will you feel faint? Explain and discuss simplifying assumptions inherent in your explanation?Thank you in advance for your quick help. Since the question is related please answer both questions together. I am repost this question again. Q1b) A stone is thrown upward at angle of 35o with a speed of 30 m/s from the top of a 40-m high building. (a) How long does it take the stone to reach the ground? (b) What is the speed of the stone just before it hits the ground?
- You slam on the gas of your racecar and you accelerate at 12 m/s2 from rest to a final velocity of 48 m/s How far will you travel during this acceleration. There IS enough information to find the answer, use your tools.please help me with drawing the Distance vs time graph for the freefall motion and the speed vs time graph and then answer the two questions on the chalk boardHi, 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?
