Question

A car setting of from trafic light(adisplacement -time graph).what dose the gradiant of the line indicate and what is the moution of the car at 1to4 s and 5to8s?

if the car travels with speed of 60km/h (avarage),how far will it travel whithin 5 h and is this avarage speed is constant speed or constant velocity?

What would be the accelaration of a car at 2 s if the speed increes from 60km/h to 65 km/h or at 2 s for bicycle which gose from zero to 5km/h?

Explanation / Answer

gradiant of the line indicate velocity of car travels with speed of 60km/h it travel whith 60*5=300km in 5 h if the speed increes from 60km/h to 65 km/h accelaration of a car at 2 s is =((65-60)/60)/2 =0.0417 km/s^2 at 2 s for bicycle which gose from zero to 5km/h =((5-0)/60)/2 =0.0417 km/s^2
