the displacement of a particle is given by the eqution S = 3t3_5t2+4t-7 Then Calculate the displacement and distance in the first 5 seconds.

Substitute t=5 to get displacement and distance ie 527

no friend that is the displacement but 4 distance its different.since the acceleration is time varying.........

Displacement and distance of a particle will be same provided the particle is having a rectilinear motion or it is moving in a straight line.
Thus the displacement and distance will be same only assuming that particle is moving in a straingt line, and is obtained by putting t = 5 in the expression of S.
Acceleration ofcourse is not constant in this case.

The Scientist does not study nature because it is useful; he studies it because he delights in it, & he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, life would not be worth living. Ofcourse I do not here speak of that beauty that strikes the senses, the beauty of qualities & appearances; not that I undervalue such beauty, far from it, but it has nothing to do with science; I mean that profounder beauty which comes from the harmoniuos order of the parts, & which a pure intelligence can grasp. |

sir the since the acceleration is not constant, the direction of motion may change..... and we can use the equatons of motion only for uniformly accelerated motion...... this will affect the distance travelled though we can find the displacement by direct substitution........
