A rigid body rotates about a fixed axis through a point in the body with uniform angular velocity of 600 rpm. The velocity then decrease at a constant to 200 rpm in 6s. Determine the angular acceleration and the extra time needed by the body to come to a stop if it continues to slow down at the same rate. ​

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

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
