Just answer #2 parts A and B please. Physics 121 HW Section 41. *C5-19: Two ropes are attached to a tree, andforces of F₁ = (2.00i + 4.00j) N and F₂ = (3.00i +6.00j)N are applied. The forces are coplanar (in the sameplane).a) What is the resultant force (net force) in unit vectornotation?b) Find the magnitude and direction of this net force.Answers: (a) (5.00 i + 10.0 j) N, (b) 11.2 N @ 63.4°2. A 0.145 kg ball, initially at rest on a tee, is hitwith a bat in the x-direction while initially 1.00meters above the ground. The ball then proceeds asa projectile, hitting the ground 20.0 meters away.(a) With what speed does the ball leave the tee?(b) If the ball was in contact with the bat for 0.700 ms(milliseconds), what average net force was exerted onthe ball during the contact time?Answers: (a) 44.3 m/s, (b) 9170 N3. The distinction between mass and weight wasdiscovered after Jean Richer transported pendulumclocks from Paris, France, to Cayenne, FrenchGuiana, in 1671. He found that they quitesystematically ran slower in Cayenne than in Paris.The effect was reversed when the clocks returned toParis.How much weight would a 90.0 kg person lose intraveling from Paris, where g = 9.8095 m/s², toCayenne, where g = 9.7808 m/s²?Answer: 2.58 N

The sun radiates energy at the rate 3.8 × 1026 W. The source of this energy is fusion, a nuclear reaction in which mass is transformed into energy. The mass of the sun is 2.0 × 1030 kg.

I'm stuck on these two questions from the same example Part C If the captain of ship A fires a missile, counts 10.0 ss on his watch, and then fires a second missile, how much time Δt will the captain of ship B measure to have passed between the firing of the two missiles? Part D The captain of ship B knows that ship A uses 2-m-long missiles. She measures the length of the first missile, once it has finished accelerating, and finds it to be only 0.872 mm long. What is the speed u of the missile, relative to ship B? Use c=3×108m/s=3×108m/s.
help me with the given question (part C And D) explain and pls pls make sure your answers are correct 100% pls and thank you !
I need help with the first 3 questions
Solve for question 3 The θ integration fails if α is non-constant. There is also a type of situation where the step before the integration fails, involving ω. Question 1: derive ω = αt + ω0. Start with the derivatives I began with, and derive this equation. Question 2: derive θ = 1/2αt2 + ω0t + θ0. You may use prior derived results. Question 3: derive θ = θ0 + (ω + ω0) t/2. You probably need to use prior derived results.
