What is the vertical component of a ball thrown at a 27 degree angle at 16 m/s?

Dominik [7]

y = y 0 + v 0 y t − 1 2 g t 2 . If we take the initial position y 0 to be zero, then the final position is y = 10 m. The initial vertical velocity is the vertical component of the initial velocity: v 0 y = v 0 sin θ 0 = ( 30.0 m / s ) sin 45 ° = 21.2 m / s .

If you feel you are about to have a collision you should ?

Mkey [24]

If you feel you are about to have a collision, you should calm yourself down and focus on the situation. It takes a second to change the happening and presence of mind is a must. It is normal to have mixed emotions, but being calm is best way to do. Hope this answers your question.

PtichkaEL [24]

Answer:

A) determine magnetic fields

For 0 ≤ r ≤ a

Magnetic field = ∅ $\frac{rI}{2\pi a^2}$

For a ≤ r ≤ b

Magnetic field = ∅ $\frac{I}{2\pi r}$

For b ≤ r ≤ c

Magnetic field in the region = ∅ $\frac{I}{2\pi r} [ c^2 - r^2 / c^2-b^2 ]$

For r ≥ c

magnetic filed in the region = 0

B ) attached below

Explanation:

<u>A) Determine the magnetic field in the following regions</u>

i) For 0 ≤ r ≤ a

Magnetic field = ∅ $\frac{rI}{2\pi a^2}$

attached below is the detailed solution

ii) For a ≤ r ≤ b

Magnetic field = ∅ $\frac{I}{2\pi r}$

attached below is the detailed solution

iii) For b ≤ r ≤ c

Magnetic field in the region = ∅ $\frac{I}{2\pi r} [ c^2 - r^2 / c^2-b^2 ]$

attached below is the detailed solution

iv) For r ≥ c

magnetic filed in the region = 0 and this is because the net current enclosed in the region = 0
