If a horizontal spring attached to a 2 kg mass is stretched 10 cm to have a spring potential energy of 50 J in 10 seconds: How much work was done to stretch this spring. (Think about the change in EPE)

How much power was done?

true

explanation:

where is the circuit diagram ?

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
