Derive the first equation of motion v = u + at, using the velocity- time graph for a body moving along a straight line with uniform acceleration.

answered-by-expert Expert Answer

Consider a velocity-time graph for a uniformly accelerated body starting from rest is represented as follows.

u: velocity at time t1

v: velocity at time t2

If acceleration is represented as a ,then, acceleration is defined as the rate of change in velocity.

This is first equation of linear motion.

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.
