a typical helicopter blade is 15 m long and had an angular velocity of 40 rad/s. How fast would the tip of the blade be moving?

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

a skateboard rolling across the street - apex

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
