A force F→ is applied to a 1.5 -kg radio-controlled model car parallel to the x-axis as it moves along a straight track. The x-component of the force varies with the x-coordinate of the car as shown below. The model car is initially at rest at x = 0. Use the work-energy theorem to find the speed of the car at the following locations. (a) x = 2.0 m m/s (b) x = 3.0 m m/s (c) x = 4.0 m m/s

A conducting rod with length 0.153 m, mass 0.150 kg, and resistance 78.9 Ω moves without friction on metal rails as shown in the following figure. A uniform magnetic field with magnitude 1.50 T is directed into the plane of the figure. The rod is initially at rest, and then a constant force with magnitude 1.90 N and directed to the right is applied to the bar. Part A How many seconds after the force is applied does the bar reach a speed of 25.9 m/s? Express your answer with the appropriate units. t =

A block of mass 0.24 kg, is placed on a flat surface inclined at angle θ relative to horizontal (as in the figure) and is initially at rest. The coefficient of static friction, μs, is 0.45 and the coefficient of kinetic friction, μk is 0.24. The angle θ is increased slowly. What is the largest value of θ (in degrees) such that you should expect the block to remain at rest and not begin to move down the incline? θmax = degrees If θ = 52 degrees and the block starts to accelerate down the incline, what is the magnitude of the acceleration? |a→| = m/s2
