A test rocket starting from rest at point A is launched by accelerating it along a 200.0-m incline at 1.80 m/s2 (Figure 1).The incline rises at 35.0∘ above the horizontal, and at the instant the rocket leaves it, its engines turn off and the rocket is subject to gravity only (ignore air resistance).

a) Find the maximum height above the ground that the rocket reaches.

b) Find the rocket's greatest horizontal range beyond point A.

Place the following list of scenarios in order from greatest energy required to least energy required, and explain using physics why you chose that order: i) A charge +q is brought in from ∞ to a distance r from a conducting sphere holding charge +Q; ii) A charge +q is brought in from ∞ to a distance r/2 from a conducting sphere holding charge +Q; iii) A charge +q is brought in from ∞ to a distance r from a conducting sphere holding charge +2Q; iv) A charge +q is brought in from ∞ to a distance r from a conducting sphere holding charge −Q; v) A charge +q is brought in from ∞ to an equidistance r from a conducting sphere of charge +Q and another sphere of charge −Q.

Consider the light passing from a means of refractive index n₁ to another of index n₂. Use the Fermat principle to minimize travel time and                                                                                     deduce the law of refraction: n₁sen (θ₁) = n₂sen (θ₂).

A 63.0 kg ice hockey goalie, originally at rest, catches a 0.150 kg hockey puck slapped at him at a velocity of 28.0 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. What would their final velocities (in m/s) be in this case? (Assume the original direction of the ice puck toward the goalie is in the positive direction. Indicate the direction with the sign of your answer.)

The rechargeable batteries for a laptop computer need a much smaller voltage than what a wall socket provides. Therefore, a transformer is plugged into the wall socket and produces the necessary voltage for charging the batteries. The batteries are rated at 9.0 V, and a current of 272 mA is used to charge them. The wall socket provides a voltage of 120 V.

(a) Determine the turns ratio of the transformer

(b) What is the current coming from the wall socket?

Three charged particles are placed at each of three corners of an equilateral triangle whose sides are of length 2.1 cm . Two of the particles have a negative charge: q1 = -8.0 nC and q2 = -16.0 nC . The remaining particle has a positive charge, q3 = 8.0 nC . What is the net electric force acting on particle 3 due to particle 1 and particle 2?

A) Find the net force ΣF⃗ 3 acting on particle 3 due to the presence of the other two particles. Report you answer as a magnitude ΣF3 and a direction θ measured from the positive x axis.
