Question

The velocity time graph of a car is shown below . find the displacement and acceleration of the car 20 km in 1 hr 2 km in 40 HR 3 km in 60km in 3hr 4 km in 80 hr
​

Answer 1

Answer:

Let the distance travelled at 100 km/hr be x km.

Then, distance travelled at 50 km/hr is (170 - x) km.

Given,

100

x

+

50

(170−x)

=2

⇒

100

x+2(170−x)

=2⇒x+240−2x=200

⇒x=140km.

∴ Distance travelled at 50 km/hr =(170−140)km=30km
