Impulse and Momentum example 2

The video tutorial explains the problem of a ball thrown vertically with an initial velocity and affected by a constant wind force. It covers the forces acting on the ball, including wind and gravity, and uses the impulse and momentum formula to calculate the ball's velocity after 4 seconds. The tutorial provides a step-by-step solution for both the X and Y components of the velocity, demonstrating the use of vector notation and integration.

What is the initial vertical velocity of the ball when it is thrown?

• 13 meters per second

• 0 meters per second

• 12 meters per second

• 5 meters per second

Which force acts constantly on the ball throughout its flight?

• Wind force

• Frictional force

• Magnetic force

• Gravitational force

What is the formula used to calculate the change in velocity of the ball?

• Newton's Second Law

• Impulse and Momentum Formula

• Conservation of Energy

• Hooke's Law

What is the horizontal component of the force acting on the ball?

• 5 Newtons

• 13 Newtons

• 9.81 Newtons

• 0 Newtons

How is the vertical component of the velocity affected after 4 seconds?

• It becomes zero

• It remains the same

• It becomes negative

• It increases

What is the final horizontal velocity component of the ball after 4 seconds?

• 13 meters per second

• 12 meters per second

• 26 meters per second

• 0 meters per second

What does a negative vertical velocity indicate about the ball's motion?

• The ball is moving downwards

• The ball is moving upwards

• The ball is moving horizontally

• The ball is stationary
