Teaching NVS TGT 2024 Test Series Physics Motion in a Straight Line Average velocity and average speed
A car travels in a straight line along a road. Its distance 'x' from a stop sign is given as a function of 't' by the equation x(t) = αt + βt3, where α = 2.0 m/s, β = 0.01 m/s3. Calculate the average velocity of the car in the time interval t = 2.00 sec to 4.00 sec.
