Force 1 is supposed to be {100.0 grams · g, 60.0o} and Force 2 is supposed to be {200.0 grams · g, 120.0o}. You will apply a third force to balance the system--how much force should you apply? Answer to three significant figures, in units of grams · g.

A heavier mass m, and a lighter mass m, are 17.5 cm apart and experience a gravitational force of attraction that is 9.00 x 10-9 N in magnitude. The two masses have a combined value of 6.00 kg. Determine the value of each individual mass. m1 Consider the product and sum of the two masses to solve for the two unknown variables. kg m2 = |kg Additional Materials еВook

An 88 kg person stands on a uniform ladder 4.0 m long, that weighs 100 N, as shown in the figure(Figure 1). The floor is rough; hence, it exerts both a normal force, f1, and a frictional force, f2, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force, f3. Figure f₁ mg f3 a-3.8 m 1 of 1 Part A Using the dimensions given in the figure, find the forces exerted on the ladder when the person is halfway up the ladder.

ma tug-of-war game on one campus, 15 students pull on a rope at both ends in an effort to displace the central knot to one side or the other. Two students pull with force 196 N each to the right, four students pull with force 87 N each to the left, five students pull with force 62 N each to the left, three students pull with force 150 N each to the right, and one student pulls with force 250 N to the left. Assuming the positive direction to the right, express the net pull on the knot in terms of the unit vector. How big is the net pull on the knot? In what direction? net pull N to the Select an answer v %3D TA 8088 ni pnibne inu

Problem 9.35 - Enhanced - with Expanded Hints An 8.5 kg crate is pulled 5.1 m up a 30° incline by a rope angled 16° above the incline. The tension in the rope is 140 N and the crate's coefficient of kinetic friction on the incline is 0.25.
