Which motions are the components of projectile motion? A and B B and C A and C None of these are correct combinations.

B and C

Explanation:

Projectile motions are the one in which an object is projected towards the earth and then due to gravitational effect it bounces and creates a curve motion. This moves an object in vertical as well as horizontal direction. The component B and C are experiencing projectile motion.

its A and B

Explanation:

real, smaller and upside-down.   so the answer should be b.

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
