and the slope makes a angle with the horizontal. If the cord is cut, what is the magnitude of the acceleration of the block?In the figure above, a block on a frictionless slope is hanging on a cord. The mass of the block is
The gravitational acceleration is
rocket sled is to be accelerated from rest to at a constant rate in seconds in outer space. What is the approximate magnitude of the required net force?A
If a point mass has an acceleration of at from the positive direction of the -axis, what is the net force in unit-vector notation?
In the movie Spiderman 2, there's a famous minute long scene where Spiderman stops a train. If the initial speed of a five-car, out of control subway train was around the top speed of the NYC subway (27 m/s), and Spiderman stopped the train in exactly one minute, then what is the magnitude of the force in Newtons that Spiderman exerted on the train as he stopped it?
Details and assumptions
kg and kg are hung on a pulley with no friction. Find the magnitude of acceleration of the left object with mass kg.In the above diagram, two objects with their respective masses
Gravitational acceleration is m/s.
