I'LL MARK BRAINLIEST PLS DON'T DELETE If F1 is equal to F2 and F4 is greater than F3, which statement is correct? (3 points)

a
An unbalanced force will move the box up.

b
An unbalanced force will move the box down.

c
Several balanced forces will keep the box stationary.

d
Several balanced forces will keep the box moving towards the right.

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

answer: b.

explanation:

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
