What two factors affect projectile motion? a) distance and angle b) distance and amplitude c) initial velocity and angle d) initial velocity and amplitude

C) Initial velocity and angle

Explanation:

The path of the projectile motion is a parabolic path. The motion of a projectile motion is studied by splitting the motion into 2 mutually perpendicular components; one along the horizontal x axis and other vertical y axis.

The position of the projectile at any time is given as:

Where,

From the above equations, we conclude that,

The projectile motion depends on two factors:

i. Initial velocity ()

ii. Angle of projection ()

Option C is correct.

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
