Answer 1

Answer:

srry bro idk

Explanation:

A driver of a car travelling at 52 km h-1 applies the brakes and accelerates uniformly in the opposite direction. The car stops in 5 s. Another driver going at 3 km h-1 in another car applies his brakes slowly and stops in 10 s. On the same graph paper, plot the speed versus time graphs for the two cars.

Answer 2

Answer:

Distance = Length of path travelled

=AB+BC

=15+9

=24km

Displacement = Shortest path from initial to final position

=AC

=

(AB)

+(BC)

=

225+81

=17.5km
