Understanding Impulse and Force in Collisions

What is the initial velocity of the bouncy ball before it hits the wall?

• 15 meters per second

• 20 meters per second

• 10 meters per second

• 25 meters per second

How is linear momentum defined in terms of mass and velocity?

• p = m + v

• p = m / v

• p = v / m

• p = m * v

What is the final momentum of the ball if its velocity is 15 meters per second to the left?

• 0.75 kilogram meters per second

• -0.75 kilogram meters per second

• 1.5 kilogram meters per second

• -1.5 kilogram meters per second

In what units can impulse be expressed?

• Kilogram meters per second only

• Both kilogram meters per second and Newton seconds

• Neither kilogram meters per second nor Newton seconds

• Newton seconds only

What is the calculated force exerted on the ball during the collision?

• -1.75 Newtons

• 1.75 Newtons

• -175 Newtons

• 175 Newtons
