Homework Statement
Given a car being pushed by a constant force:
a. How will the acceleration change in relation to the mass of the car? --> Done, it'll decrease
b. How will a graph of acceleration in the y-axis and and (1/m) being the x-axis will look like? What will the slope of the...
So a = - g for upward becomes a = g for downward, (with g = 9.80 m/s^2) and what would be vo = + for upward becomes vo = - for downward, or what? Also, y = 0 is the exact last point of the diving board in the way I'm trying to make the exercise.
I uploaded a diagram for reference.
Homework Statement
A high diver leaves the end pf a 5.0-m high diving board and strikes the water 1.3s later, 3.0m beyond the end of the board. Determine his inicial velocity, his maximum height and the velocity with which he enters water. (Projectile Motion).

Right. My bad, I forgot to write that last part of the instructions.
Obviously, given the z<0 part of the answer and the domain of the function, then the first two shall be negative and the last one will be positive.
It was as I thought, so thank you for clearing that out. Sucks when you...
Let's take this one step at a time. You know the formula for modeling something that changes with time is F(t) = Changing Variable times t + Initial State, right?
If you know the Initial State (Height) of the Balloon, then what else needs to be placed in the function?
Set F(t) to the height...
Homework Statement
Be x an element in the interval [Pi/4, 3Pi/4] express cos(2x), sin x, sin (x+pi) in terms of x. You must know that, for this question, cos x = z and z will always be < 0.
Homework Equations
cos(2x) = 2 (cos(x))^2 - 1
cos(2x) = cos^2 x - sin ^2 x
sin^2 x + cos ^2 x = 1...
