1. what is the displacement of the car between 0s and 24 s? 2. what is the distance of the car between 0s and 24s?

1). Displacement = 24 m

2). Distance = 28 m

Explanation:

We will use the concept that distance is a scalar quantity and displacement is a vector quantity.

1). Displacement of the car between 0 s and 24 s

  Displacement = distance between origin (0, 0) and a point on x - axis (24, 0)

                          = 24 - 0

                          = 24 meters

2). Distance traveled by the car = Distance traveled by the car on the ramp

    = Distance traveled on the tracks (AB + BC + CD)

    AB =

          =

          =

          = 10 m

    BC = 16 - 8

          = 8 m

    CD =

          = 10 m

     Therefore, distance traveled by the car = 10 + 8 + 10

                                                                        = 28 m

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
