Answer #1

1) displacement from o to as ds: under v-t graph from o to 2s I (lm/s +3m/s) (25) area = 2 4m 2 to 6s displacement from d2= a2) Initially the speed is constant which means that net force is zero. This means that the horizontal force applied is equal to friction force on the box. When the woman doubles the applied force, the net force is in direction of the applied force and has value greater than zero. Hence there will be a finite acceleration and speed will start increasing. Hence, the correct option is: with a continuously increasing speed.

    A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...
