f net would actually be mgsin theta. I am doing the problem right now on an online program and for that part of the problem it said that i got it right. so those are the knowns, mgsintheta for the net forces and mgcos theta for the normal force between the block and the wedge.
Homework Statement
A wedge with an inclination of angle theta rests next to a wall. A block of mass m is sliding down the plane, as shown. There is no friction between the wedge and the block or between the wedge and the horizontal surface. (Intro 1 figure) what is the magnitude of the force...
Homework Statement
In an atwood machine which is a pulley with two wieghts attached to it (m1 and m2), m1= m2, how much tension is found on the string? I thought that it would be zero tension on the string but that appeared to be wrong. How would you solve it?
The Attempt at a Solution
sorry but as i said before i have no clue as to how to solve this problem i added the two forces to find part 3 but i got 16.6 which turned out to be wrong. I have a problem in seperating the forces into an x and y component. How exactly do you go about doing that when you are given a problem...
Homework Statement
Two forces, F_1 and F_2, act at a point. F_1 has a magnitude of 9.60 N and is directed at an angle of 61.0 degrees above the negative x-axis in the second quadrant. F_2_vec has a magnitude of 7.00 N and is directed at an angle of 53.7 degrees below the negative x-axis in the...
Homework Statement
Ive have tried it so many times but can't get the right answer but the problem is: Your roommate is working on his bicycle and has the bike upside down. He spins the 54.0 cm-diameter wheel, and you notice that a pebble stuck in the tread goes by three times every second...
Hello i need help with this problem where i am only given the maximum height and range. The problem is that a rocket reaches a height of 72.3 meters and had a maximum range of 111 meters. What is the launch angle? and what is the launch speed?
Does anybody know how to solve it
