A body has a initial velocity 4 m/s and deceleration of 4m/s2. What is the final velocity after travelling 2m?
v2 = u2 – 2as
u= 4m/s, a = 4m/s2 and s = 2 m,
So, v = 0m/s
A body has an initial velocity 4 ms−1and its final velocity is 1 ms−1, then what is the acceleration after traveling 2m?
A body has an initial velocity of 4 ms−1 and deceleration of 4 ms−2, then what is its final velocity after travelling 2 m?
A ball of mass 4 kg moving with a velocity of 12 m/s impinges directly on another ball of mass 8 kg moving with velocity of 4 m/s in the same direction. Find their velocities after impact (if e = 0.5)
