The momentum before a collision of three objects is always greater than the momentum after the collision. true or false

false

Explanation:

The law of momentum states that the momentum of objects before collision is equal to the momentum after collision.

So when the three objects collide the momentum still remains the same and didn't change

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
