Which of the following statements is true in the case of a collision? OA.
Increased impact time will increase the impact force.
OB.
Reduced impact velocity will increase the impact force.
Ос.
Reduced impact mass will increase the impact force.
OD
Reduced impact time will increase the impact force.

D

Reduced impact time will increase the impact force

Explanation: Collision occurs when two or more bodies collide and exert forces on each other within a short time.

If a body of mass M moving with a velocity V collide with another body, the kinetic energy of the body is equal to the work done by the body.

That is, K.E = 1/2mv^2 = F × s

Where workdone = Force × distance

Make F the subject of formula

Mv^2/2s = F

But V = distance s/time t

Substitute for V

Ms^2/2t^2s = F

Ms/2t^2 = F

From the equation above, we can deduce that F is inversely proportional to the square of time.

Therefore, the reduced impact time will increase the impact force

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
