what is the acceleration?
Hey guys, Hope someone can give me a hand on this one? A particle is subjected to undamped harmonic oscillation described by the equation: x=sinωnt Prove that the linear acceleration...
I need help with this problem i have no clue where to even begin with it. Everything i try is the wrong answer.
Consider the 620 N weight held by two cables. The left-hand cable had tension T and makes an angle of θ with the wall. The right-hand cable had tension 910 N and makes an angle of 26 ? with the ceiling...
A 1351.9 kg car is traveling at 22 m/s when the driver takes his foot off the gas pedal. It takes 4.2 s for the car to slow down to 20 m/s. How large is the net force slowing the car? Answer in units...
My teacher gave us this problem and i am unsure on how to solve for the direction of the angular acceleration. Mr. Foster is riding a bicycle eastward on a bicycle when he reaches...
A force is applied to a 1.4 kg mass and produces 2.4 m/s2 acceleration. What acceleration would be produced by the same force applied to a 6.3 kg mass? Answer in units of m/s2.
I'm not sure how to solve for radial speed. The farthest I can get is solving for the circumference of the circle which is 2*pi*r or 2*3.14*22=138.2
I know that W=FXD but in that case that mean that the work done for this problem is 2 joules. Is that right?
I am struggling to solve this problem and i have tried to look it up on how to solve it and i'm clueless. I would appreciate some help solving this problem.
The mass of the heavier block is 24 kg and the mass of the lighter blocks is 12 kg and the magnitude of the force of the connecting string on the smaller block is 16 N. Assume: g= 9.8 m/s2 and μ=...
Consider the 683 N weight held by two cables shown below. The left-hand cable hadtensionT2and makes an angle of 40? with the ceiling. The right-hand cable had tension T1 and makes an angle of 52?...
This is one of the questions on my review guide my teacher gave me and I have a test tomorrow and have no idea how to find the answer to this question! If someone could give the formula to find mass...
A target lies flat on the ground 10 m from the side of a building that is 10 m tall, as shown below.The acceleration of gravity is 10 m/s2.Air resistance is negligible. A student rolls a 10 kg ball...
A plane drops a hamper of medical supplies from a height of 3950 m during a practice runover the ocean. The plane’s horizontal veloc-ity was 117 m/s at the instant the hamper was dropped. The acceleration...
