Answer:
Explanation:
Let assume that the solid cylinder rolls down a frictionless incline. The translational speed can be found by using the Principle of Energy Conservation and the Work-Energy Theorem:
The translational speed is:
Two particles, with identical positive charges and a separation of 2.85 x 10⁻² m, are released from rest. Immediately after the
release, particle 1 has an acceleration vector a₁ whose magnitude is 4.50 x 10³ m/s², while particle 2 has an acceleration vector a₂ whose magnitude is 8.15 x 10³ m/s². Particle 1 has a mass of 6.40 10⁻⁶ kg.

Answer:
<em>The first choice (32m/s) is the closest to the answer</em>
Explanation:
The magnitude of a vector is the distance between the initial and the end point of the vector.
Being Vx and Vy the horizontal and vertical components of the vector V respectively, the magnitude of V is calculated as:
The components of the velocity of the physics student's projectile launcher are Vx=28 m/s and Vy=15 m/s.
Calculate the magnitude of the velocity:
The first choice (32m/s) is the closest to the answer
