Consider a car initially at rest, starts to move along a straight road first with acceleration `5 m//s^2`, then with uniform velocity and finally, decelerating at `5 m //s^2` , before coming to a stop . Total time taken from starts to end is t= 25 s . If the average velocity during that time is 72 km/ hr , the car moved with uniform velocity for a time of

Consider a car initially at rest, starts to move along a straight road first with acceleration 5 m/s^2, then with uniform velocity and finally decelerating at 5 m/s^2, before coming to stop. Total time taken from start to end is t = 25s . If the average velocity during that time is 72 km/hr, the car moved with uniform velocity for a time of

A car starts moving along a line, first with acceleration a=5 ms^(-2) starting from rest then uniformly and finally decelerating at the same rate a, comes to rest.The total time of motion is tau=25 s . The average velocity during the time is equal to lt v gt =72 km/hr.How long does the partial move uniformly ?

A car start moving along a line, fisrt with acceleration a=5 ms^-2 starting from rest then uniformly and finally decelerating at the same rate a, comes to rest. The total time of motion is pi=25s. The average velocity during the time is equal to lt v gt =72 km/hr . How long does the particle move uniformly ?

A car starts moving along a line, first with acceleration a=5m//s^(2) starting from rest then uniformly and finally decelerating at the same rate till it comes to rest. The total time of motion is 25s . The average speed during the time is 20m//s . The particle moves uniformly for (2.5x) second. Find the value of x .

A car starts moving rectilinearly first with acceleration alpha=5 m s^(-2) (the initial velocity is equal to zero), then uniformly, and finally, deceleration at the same rate alpha comea to a stop. The time of motion equals t=25 s . The average velocity during this time is equal to =72 km h^(-1) How long does the car move unitromly?
