What is the magnitude of the net force, in newtons?
What is the angle e, in degrees, of the net force, measured from the +x-axis? Enter an angle between -180° and 180°.
What is the magnitude, Ja of the acceleration, in meters per square second, if the block has a mass of 8.9 kg?
consider a force vector = 300 g at the 40º angle. resolve this vector into its x- and y-components by the following methods: a) graphical: make the x- and y-axes. use a scale of 30 g = 1.0 cm, and draw an arrow of appropriate length at 40º. drop perpendiculars from the tip of the vector to the x- and y-axes. measure the lengths of these lines and hence find the magnitudes of fx and fy. (do not calculate using trigonometry) record the results. b) analytical: compute the magnitudes of fx and fy by using the component method (equations 3-3 and 3-4). record the results.

- A dancer is standing on one leg on a drawbridge that is about to open. The coefficients of static and kinetic friction between the drawbridge and the dancer's foot are μs and μk, respectively. n⃗ represents the normal force exerted on the dancer by the bridge, and F⃗g represents the gravitational force exerted on the dancer, as shown in the drawing.(Figure 1). For all the questions, we can assume that the bridge is a perfectly flat surface and lacks the curvature characteristic of most bridges. Before the drawbridge starts to open, it is perfectly level with the ground. The dancer is standing still on one leg. What is the horizontal component of the friction force f⃗? (Express your answer in terms of some or all of the variables n, μs, and/or μk.) (Figure 2). The drawbridge then starts to rise. The dancer continues to stand on one leg.
