A common example of constant acceleration is gravity; i.e., a body freely falling toward earth. Solution: According to the question the initial velocity , u =20m/s, Since the body is coming to rest that means the final velocity, v= 0 m/s, Time taken by the body to come to rest, t=5 sec, So, applying the first equation of motion we get, v= u +at, i.e 0=20 + 5a. That is indeed the case here, so you can be assured that the answer is correct. Therefore, equation (1) becomes If we wish to find an equation that doesn't involve time t we can combine equations (2) and (3) to eliminate time as a variable.

The earth for example may be assumed as a particle in comparison with its orbit, whereas to an observer on the earth, it is a body with appreciable size. We can infer the value of the final velocity v to be 0 m/s because the final state of the toy is the peak of its trajectory. Calculate the height to which the toy will rise above its initial height. In this case, we can infer the value of v to be 0 m/s because the car is initially at rest. For the latter, you can substitute the calculated value of S back into the equation and see that both sides of the equation are identical. A system of particles which formed into appreciable size is termed as body.
