18 year old Bianca ran sprints for 30 seconds as fast as she could run, then checked her pulse abd realized it was 8 beats above her maximum heart rate. What was her heart rate?

210

Explanation:

A person's estimated maximum heart rate is 220 minus their age. Since she is 18, her maximum is 220 - 18 = 202. As hers was 8 beats over her maximum, simply add 8 to 202 to find 210 as her heart rate.

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
