Question

How do you calculate the velocity of a 110-pound guy tackling a 100-pound guy who are 20 feet apart?

A) Use the equation v = d/t, where v is velocity, d is distance, and t is time.
B) Calculate the potential energy of both guys and then find their kinetic energy to determine velocity.
C) Use the equation v = m*d/Δt, where m is mass, d is distance, and Δt is change in time.
D) Find the acceleration due to gravity and apply it to the guys to calculate velocity.

Answer 1

To calculate the velocity of the 110-pound guy tackling the 100-pound guy who are 20 feet apart, we can use the equation v = d/t, where v is velocity, d is distance, and t is time. By considering the initial velocities and applying the principle of conservation of momentum, we can find the final velocity of the combined system. To find the time it takes for them to collide, we can use the equation v = d/t.

Step-by-step explanation:

To calculate the velocity of the 110-pound guy tackling the 100-pound guy who are 20 feet apart, we can use the equation v = d/t, where v is velocity, d is distance, and t is time. To find the time it takes for them to collide, we need to consider the initial velocities of both guys and the acceleration they experience upon collision.

Let's assume that both players are moving horizontally and in the same direction. Player A (110 pounds) has an initial velocity of vA and player B (100 pounds) has an initial velocity of vB. When they collide, their combined mass is 110+100=210 pounds.

Applying the principle of conservation of momentum, the initial momentum of player A and player B is equal to the final momentum of the combined system. Using the equation (mA*vA + mB*vB) = (mA+B*vfinal), we can solve for vfinal.

Once we have the value of vfinal, we can plug it into the equation v = d/t, along with the distance d = 20 feet, to find the time it takes for them to collide.
