Question

rolling ball moves from x1 = 8.2 cm to x2 = -4.5 cm during the time from t1 = 2.8 s to t2 = 6.7 s

science physics

Answer 1

Answer #1

Average velocity, v = (x2 - x1)/(t2 - t1)

V = (-4.5 - 8.2)/(6.7 - 2.8) = 3.26 cm/sec

A car moves along a straight street. The car’s initial position at time t1 is given by a position vector x! . The car’s later position vector is x2! at time t2. Suppose x1! = 700 miˆ . and x2! =400miˆ. a. If t2 – t1 = 3.0 seconds, what is the car’s average speed (assuming the car only moved in one direction)? b. What was the car’s average velocity?
