Question

An object of mass m = 0.300 kg is suspended from the ceiling of an accelerating truck as in the figure below. Take a = 2.80 m/s2. A truck is accelerating to the right, as indicated by an arrow labeled vector a. A small sphere of mass m is suspended from the ceiling of the truck by a string. The string makes an angle θ with the vertical, and the mass hangs to the left of the vertical. (a) Find the angle θ (in degrees) that the string makes with the vertical. ° (b) Find the tension T (in N) in the string. N What If? The truck returns to a constant velocity so that the mass hangs straight down inside the truck, whereby θ = 0. Later, the truck carefully slows down. During this braking maneuver, the string is observed to make a constant angle of θ = 23.0° with the vertical. (c) What is the acceleration of the truck (in m/s2) while it is braking? m/s2 (d) What is the direction of the deflection of the string while the truck is braking? forward backward
