The speed of a car increases uniformly from zero to `10ms^-1` in `2s` and then remains constant (figure)

a. Find the distance travelled by the car in the first two seconds.
b. Find the distance travelled by the car in the next two seconds.
c. Find the total distance travelled in `4s`.

Text Solution

Verified by Experts

a. Distance=area`=1/2xx2xx10=10m`
b. Distance =area=`2xx10=20m`
c. Total distance `=10+20=30m`
