A player passes a basketball to another player who catches it at the same level from which it was thrown. The initial speed of the ball is 7.2 m/s, and it travels a distance of 4.7 m a.) What was the initial direction of the ball? (Express your answer using two significant figures. If there is more than one answer, separate them by a comma) b.) What was its time of flight?

youtube.com/watch?v=srDeACrSf-o&t=12s In the video, I drop a ball off a three-story balcony. We know that objects in freefall follow the equation for height h, in meters, h=−4.9t2+ch=-4.9t2+c, where t is time in seconds, and c is the initial height. A student timed the drop at 1.51 seconds.Use this to determine the height from which the ball was dropped, to at least 2 decimal places.
Part 1: A motorist traveling at 17 m per s encounters a deer in the road 48 m ahead. If the maximum acceleration the vehicle's brakes are capable of is -5 m per s2 what is the maximum reaction time of the motorist that will allow her or him to avoid hitting the deer? Answer in units of s. Part 2: If his or her reaction time is 1.29353s, how fast will (s) he be traveling when(s)he reaches the deer? Answer in units of m per s.
2. Can you please THOROUGHLY explain how did you solve this? I need it in step by step format because I'm going to explain it in class. Please help me, thank you
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.

Hi I am in phyiscs I and it has the problem a runner ran the marathon (approx. 26.1) in 2 hours and 57 min. What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please detalied steps of how to solve this so I can understand it. Thank you!
