A kickoff sends a football with an initial velocity of 25 m/s at an angle of 50
1 answer:
Answer:
The x-component of the velocity is 16.07 m/s
The y-component of the velocity is 19.15 m/s
Explanation:
Given;
initial velocity of the football, u = 25 m/s
angle of projection, θ = 50⁰
The x-component of the velocity (horizontal component) is given as;
The y-component of the velocity (vertical component) is given as;

The acceleration of the electron is larger than the acceleration of the proton.
The reason for this is that the mass of the electron is smaller (about 1000 times smaller) than the mass of the proton. The two particles have same charge (e), so they experience the same force under the same electric field E:
However, according to Newton's second law, the force is the product between the mass particle, m, and its acceleration, a:
which can be rewritten as
we said that the force exerted on the two particles, F, is the same, while the mass of the electron is smaller: therefore, from the last formula we see that the acceleration of the electron will be larger than that of the proton.
