Arocket is fired at a speed of 75.0 m/s from ground level, at an angle of 60.0° above the horizontal. the rocket is fired toward an 11-0m-high wall, which is located 27.0 m away. the rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. by how much does the rocket clear the top of the wall?

ΔH = 33.17m

Explanation:

By knowing the amount of time it takes the rocket to travel the horizontal 27m, we will be able to calculate the height when x=27m. So:

  where

Solving for t:

t=0.72s

Now we calculate the height of the rocket:

If the wall was 11m-high, the difference is:

ΔH = 33.17m

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
