ACCELERATION SI UNIT IS M/S2 AND VELOCITY M/S. HOW AND WHY
Asked by | 27 May, 2008, 02:36: PM
answered-by-expert Expert Answer

Velocity of a body is the distance travelled by it per unit time in a given direction. SI unit of distance is metre (m) and of time is second (s); hence the SI unit of velocity is meter per second (m/s)

Acceleration of a body is defined as the rate of change of its velocity with time. SI unit of velocity is metre per second (m/s) and of time is second (s); hence the SI unit of acceleration is metre per second square (m/s2)

question 1) A body is projected vertically upwards from top of the tower with the velocity of 30m/s. if it takes 8sec to reach on ground then what is the height of the tower (g=10ms). what is the total distance travelled by the body. question 2) A body is dropped from the height of h covers by 64% distance in its last second.find out thte total tim of the ball and height. question 3) A body projected vertically upward, At the half  of its maximum height its velocity becomes 20m/s, what is the maximum height attained by the body. question 5) A body is projected vertically upward from ground. the time of flight is 8 sec find the velocity of projection.
