Explanation:
Detailed explanation-1: -⇒v=√37ms. Q. A body with an initial velocity of 18 kmph accelerates uniformly at 9 cms−2 over a distance of 200 m.
Detailed explanation-2: -A body moving along a straight line at 20m/s undergoes an acceleration of 4m/s2. After two seconds, what will its speed will be, exactly after 2seconds? Final speed, v =? Thus, after two seconds, the speed will be 28m/s.
Detailed explanation-3: -Because acceleration is velocity in m/s divided by time in s, the SI units for acceleration are m/s2, meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second. Was this answer helpful?
