What is the velocity of the projectile when it hits the net?

Therefore, the value of vy1, which is 19.0 m/s, must be the maximum value of the vertical component of velocity. In summary, the Great Projecto is launched from a cannon at a velocity of 29.8 m/s at an angle of 50.4 degrees. He lands in a net 2.0 m above his starting elevation. The maximum velocity he reaches is 19.0 m/s in the vertical direction.

Homework Statement


The Great Projecto is fired from a cannon at a velocity of 29.8 m/s at an angle of 50.4 degrees. He lands in a net which is 2.0 m above his starting elevation. What is his velocity when he hits the net? How do I find it with no starting elevation?
vx1: 36.02 m/s vy1: 19.0 m/s
vy2=?
vx2: 36.02 m/s a= -9.8/ms
a=0

Hi gungo, Welcome to Physics Forums.

You need to make an attempt at solution in the indicated area of the template. Even if you can't solve the problem completely or correctly, you should at least be able to write down relevant equations for this type of problem.

If you look carefully at the problem statement you will see that he lands 2.0 meters above his starting elevation. So pick any starting elevation you like.

The magnitude of one component of velocity cannot exceed the magnitude of the overall velocity.
 

1. What is projectile motion?

Projectile motion is the motion of an object through the air or space under the influence of gravity. It follows a curved path known as a parabola.

2. How is projectile motion different from regular motion?

Projectile motion involves two components of motion: horizontal and vertical. While the horizontal component remains constant, the vertical component changes due to the force of gravity.

3. How is the initial velocity of a projectile calculated?

The initial velocity of a projectile can be calculated by using the equation v0 = vx0 + vy0, where v0 is the initial velocity, vx0 is the horizontal velocity, and vy0 is the vertical velocity.

4. What factors affect the trajectory of a projectile?

The trajectory of a projectile is affected by its initial velocity, angle of launch, air resistance, and mass of the object. Other external factors such as wind and elevation may also play a role.

5. How can projectile motion be applied in real-life situations?

Projectile motion is used in various real-life situations such as ballistics, sports, and space exploration. It helps in predicting the trajectory of objects, such as a cannon shot, and is also used in designing efficient structures like bridges and buildings.
