A 20 kg mass starts at rest and has two forces acting on it: F1 & F2. F1 = (13.0 N,32.0 N) and F2 = (-32.0 N.-13.0 N). How far does this object travel after 9 seconds? Report you answer to the nearest meter.
Three forces acting on an object are given by # = (-2.21 + 7.155) N, F2 = (4.559 – 2.55) N, and F3 = (-49.51) n. The object experiences an acceleration of magnitude 3.95 m/s2 (a) What is the direction of the acceleration? 5.6 x Note that the direction of the acceleration is the same as the direction of the net force. (counterclockwise from the +x-axis) (b) What is the mass of the object? 12.0 kg (c) If the object...
Three forces acting on an object are given by F1-(-2.05 i-2.50 j) N, F2 -(4.70i-3.15j)N, and F3-(-40.5 i)N. The object experiences an acceleration of magnitude 3.75 m/s2. (a) What is the direction of the acceleration? (b) What is the mass of the object? (c) If the object is initially at rest, what is its speed after 10.0 s? (d) What are the velocity components of the object after 10.0 s? X (from the positive x axis) kg m/s j) m/s
find F2 in vector notation using mass, F1, velocity. Assume that these are the only two forces acting upon it.
