The kinetic energy acquired by a body of mass m is travelling some distance s , starting from rest under the action of a constant force, is directly proportional to?

the answer is to check all of them! they all apply well at least i think so!

compass can be used day and night, cloudy or sunny

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
