PLEASE HELP I'M STRUGGLING REALLY BADLY Fifteen seconds into a car race, a car runs through a checkpoint that is 250 m [N] from the starting point. Thirty-six seconds into the race it runs through another checkpoint that is 750 m [N] from the starting point. Determine the average velocity of the car between the two checkpoints.

The answer is 24m/s but id. k how to get that pls explain
NO LINKS I WILL REPORT U

Explanation:

24m is a national anthem in the United States and the world of America is the most important part of the world in which you can tell my Saturday was

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
