Question

A body is projected vertically upward with a velocity of 21 m second find Maximum height , time taken by it to reach this height the velocity with which it passes a point at a height of 10 m

Answer 1

Answer:

A body is projected vertically upwards with a velocity of 21m/s. Find a) the maximum height reached by the body b) the time taken by it to reach this height c) the velocity with which it passes a point A at a height of 10m. d) the time that elapses when the body passes through A on its downward joumey from th instant of projection. g = 9.8m/s (22.5 m: 2.14 s 15.65m/s; 3.745 s From the top of a structure 100m high, a body is projected vertically

Answer 2

Answer:

It is a little difficult. But let us try. I shall request the moderator to not delete the answers. Okay, lets start.

its h=100m as it goes up and then comes down.

its v will not be 9.8, it shall be -9.8
