At t = 0.0 s, a runner is moving forward (in the positive direction along the x-axis) at a
speed of 7.0 m/s. for 2.0 s the runner accelerates to his left at 0.50 m/s2
and backward
at 1.0 m/s2
. what is the runner’s position at t = 2.0 s in terms of the component
directions (forward/back and left/right)?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied. true or false

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question
