An object of mass m is subjected to three forces: F1, F2, and F3. In the right figure, the three forces are shown in their respective directions. The forces F1 and F3 have a magnitude of F, while F2 has a value of 2F. What is the object's acceleration? Remember that an acceleration is a vector and express it in terms of F and m.
An object of mass m has these three forces acting on it . F1, F2, and F3 are shown in the figure. Assume the x-direction is to the right, and the y-direction is straight upwards.
Let F1 = 7 N, F2 = 9 N, and F3 = 2 N.
What is the magnitude a of the acceleration in meters per second squared, if the object has a mass of 7.9 kg?
A man pushes a 49 kg block of ice in the positive direction across a frozen lake as shown in the picture. The coefficients of static and kinetic friction are μs=0.1 and μk=0.03.
