Question

A toy rocket is launched vetically upward, when the object is on its highest point its velocity is at its maximum.
True or false

Answer 1

The velocity should be zero at its highest point. The initial and final velocity would be the maximum.

Answer 2

It will be 0 at the top of its flight path since it has to change direction to come back down. Contrary to cclark's reply, it's maximum velocity will not be the same as its initial/final velocity since those are both 0. The maximum velocity depends on its acceleration on the way up (along with drag and change in mass due to fuel being consumed).

Answer 3

For simple physics such as this, drag and mass are typically disregarded. For an ideal situation of vertical motion, Vmax is at the beginning and end.

Answer 4

Yea, drag and mass are typically disregarded in early Physics...and rockets can magically and instantaneously launch at 100m/s :)

Answer 5

Thank to both of you, according to the instructions if its false I need to change the word maximum, should I write the word minimum instead

Answer 6

yes
