A1000-kg car traveling north at 15 m/s collides with a2000-kg truck traveling east at 10 m/s. the occupants, wearing seat belts, are uninjured, butthe two vehicles move away from the impact point as one. the insurance adjuster asks youto find the velocity of the wreckage just after impact. what is your answer?

8.33 m/s, 36.87° North of East

Explanation:

= Mass of car = 1000 kg

= Velocity of car = 15 m/s

= Mass of truck = 2000 kg

= Velocity of truck = 10 m/s

M = Combined mass = 1000+2000 = 3000 kg

Momentum

Momentum of car traveling East is 15000 kgm/s

Momentum of truck traveling North is 20000 kgm/s

Angle

As the two vehicles are vectors, the resultant velocity is

Velocity of the two vehicles when they are locked together is 8.33 m/s and direction is 36.87° North of East

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.
