Question

2. A rocket is launched from rest, at ground level. The graph of the rocket's velocity with respect to

time looks as follows: y= 0.15x2
How fast is the rocket traveling after 15 seconds?
Insert the graph picture here:
Graph please

Answer 1

y = 33.75 m/s.

Explanation:

The graph of the rocket's velocity with respect to time looks as follows :

`y=0.15x^2` ...(1)

Where x is time in seconds

We need to find the velocity of rocket after 15 seconds. Put x = 15 in equation (1).

`y=0.15* (15)^2\\\\=33.75\ m/s`

Hence, the speed of the rocket after 15 seconds is 33.75 m/s.
