Bambi is walking along the train tracks when he suddenly notices a fast approaching train and freezes in his tracks like a deer in headlights. IF the 1000kg train collides with Bambi at a speed of 8 m/s, and Bambi, who weighs 75kg, gets stuck to the front of the train, how fast will the train and Bambi continue to move after the collision

The final speed of the train and Bambi after collision is 7.44 m/s

Explanation:

Given;

mass of the train, m₁ = 1000kg

mass of  Bambi, m₂ = 75kg

initial speed of the train, u₁ =  8 m/s

initial speed of Bambi, u₂ =  0 m/s

If Bambi gets stuck to the front of the train, then the collision is inelastic.

m₁u₁ + m₂u₂ = v(m₁ + m₂)

where;

v is the final speed of the train and Bambi after collision

Substitute the given values and solve for v

1000 x 8 + 75 x 0 = v (1000 + 75)

8000 = v (1075)

v = 8000/1075

v = 7.44 m/s

Therefore, the final speed of the train and Bambi after collision is 7.44 m/s

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.
