3) Two bumper cars of masses 600 kg and 900 kg travelling (on a smooth surface) with velocities 8m/s and 4 m/s
respectively, have a head on collision. If the coefficient of restitution is 0.5. a) What sort of collision is this? b)
Calculate their velocities immediately after collision. c) If the coefficient of restitution was 1 instead of 0.5, what
is the amount of energy lost during collision?
The rectangular loop of wire shown in the figure (Figure 1) has a mass of 0.18 g per centimeter of length and is pivoted about side ab on a frictionless axis. The current in the wire is 8.5 A in the direction shown. Find the magnitude of the magnetic field parallel to the y-axis that will cause the loop to swing up until its plane makes an angle of 30.0 ∘ with the yz-plane. Find the direction of the magnetic field parallel to the y-axis that will cause the loop to swing up until its plane makes an angle of 30.0 ∘ with the yz-plane.
Give a more general expression for the magnitude of the torque τ. Rewrite the answer found in Part A in terms of the magnitude of the magnetic dipole moment of the current loop m. Define the angle between the vector perpendicular to the plane of the coil and the magnetic field to be ϕ, noting that this angle is the complement of angle θ in Part A.
Give your answer in terms of the magnetic moment mm, magnetic field B, and ϕ.
