The velocity- time graph of car moving on a straight track is given below. The car weight 1000kg.
The distance travelled by the car during the whole motion is:

A

50m

B

75m

C

100m

D

150m

Text Solution

Verified by Experts

The correct Answer is:
B

Distance travelled by the car in 10 second and it is same as area under the v-t curve.
`:. Distance =1/2xx2xx10+10xx5+1/2xx3xx10`
`=10+50+15`
`=75 m`
Hence(B)
