A cyclist bikes in a straight line at an average velocity of 22 miles/hour east and I’m finishing a 100 mile race how much time did it take her

Below

Explanation:

To calculate the time it took for the cyclist to finish their race, you can you this equation :

     time = displacement / velocity

Plug in your values

     time = (100 mi) / (22 mi/h)

             = 4.54545454 hours

As for sig figs in this question you would need to round this answer to 1 sig fig because 100 only has 1 sig fig. (you round to the lowest # of sig figs in the question)

     = 5 hours

It took the cyclist 5 hours to complete their race

Hope this helps! Best of luck <3

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
