This is quite efficient to compute the integral. ;)

Have you heard about Right-Hand Rule or Left-Hand Rule? Those rules are related to the problem you are stuck in.

Very well done!

We can help you, but we can't answer the question for you since it's important for students to work out the problem by themselves. Based on the problem, we know that since the sum of ##t_7## and ##t_8## is ##5832## and the sum of ##t_3## and ##t_2## is ##24##, we have ##t_2 + t_3 = 24##...

Did you show the work here? I asked this question because I want to see how you approached this problem. Other than that, the answer is not ##3.8##. I recommend you start this problem by indicating all available info you have.

You are correct; the answer is ##\frac{bt^3}{3}##. Try integrating ##bt^2##, treating ##b## as the constant, by calculus. Which rule do you need to use to integrate such an expression? This is one of the elementary derivative rules.

You didn't multiply ##e^{-\frac{|t|}{t_c}}## by itself. Instead, the second multiplier misses the negative sign. Check your work carefully and try again evaluating the integral.

Your equations are mostly correct, but you forget the ##t## variable next to ##v_i\sin(35^{\circ})##. That is because the ##y##-component distance formula is ##y(t) = y_0 + v_i\sin(\theta)t + \dfrac{1}{2}gt^2##. Be sure to first express in that form.

If you place an object on the hill at some height ##h##, then it only has a potential energy, which is a total energy. Let it go, so without friction, the moving object, which makes back at a height ##h##, has that amount of potential energy and reaches zero velocity. However, zero velocity at...

Next time to use the HW template, so the post is well-organized. For your answers to the problem, yes they are right.

Be sure to use the HW template, which every user must use to get HW Help. You also need to know what you tried so far, so we can assist you.

Some hints: Draw the diagram and then use the formula. What do you know about the x-distance and y-distance?

It would be a lot easy if you upload the free-body diagram of that plane, so we can really help you.

Nicely done. ;) Finally, determine the magnitude of ##\vec{C}##, and you are done.

First start is the body diagram. Indicate what you know from the problem.
