Which of the following is a true

Energy cannot be changed from one form to another.

Energy can change from one form to another.

Energy can only change into heat energy.

Energy can be produced by living things.

Energy can change from one to another

Explanation: Think about riding a bike, you use energy right? When riding a bike at constant speed, only kinetic energy of the air disturbed by the bicycle/cyclist's motion is generated. This kinetic energy is then dissipated in fairly short order. So when you ride your bike you hope that the muscular (chemical) energy is converted mainly into mechanical energy.

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
