The diagram above shows the path of a vehicle as it moves from A to B and then proceeds to C. AB is 37.09m and BC is equal to 58.44m. It takes the vehicle 17.00s to reach B from A and another 12.50s to arrive at C.

a. Calculate the total distance travelled. [1]

b. Calculate the speed of the vehicle from A to B. [2]

c. Calculate the speed of the vehicle from B to C. [2] 

d. What is the average speed of the vehicle as it goes from A to C. [4]

e. If the vehicle went directly from A to C in a straight line, it would travel 38.00m due South in 16.98s.

     i.  What would be its displacement? [1]

    ii.  What would its speed be in this case? [3]

   iii.  What would be its velocity. [1]

A child throws a ball vertically upwards at an average velocity of 2.34±0.02m/s. The ball returns to the child's hand after 1.5±0.3s.

a. What is the range of vertical velocity? [2]

b. What is the range of time interval? [2]

c. Determine the distance travelled. (take uncertainties into account)[7]
