Question

A rocket's acceleration is 6.0 m/s2. assuming it starts at 0 m/s, how long will it take for the rocket to reach a velocity of 42 m/s?

Answer 1

Alright! Here's how we do it, the rockets acceleration is 6 m/s^2. This means that for every second that goes by, the rocket increases it's speed by 6 m/s. So, you simply divide 42 by 6:

42/6 = 7.

So assuming the rocket starts at 0. The rocket will take 7 seconds to reach the velocity of 42 m/s.

Answer 2

7 seconds

Step-by-step explanation:

There are many formulas that can be used. For this example, we can use the formula:

v = u + at (where v = final velocity; u = initial velocity; a = acceleration ; t = time)

We are given the acceleration, initial and final velocity, so we are left with one unknown, which is time.

We rearrange the formula to make time the subject of the formula, and then solve for t:

t = (v - u) / a

t = (42 m/s - 0 m/s) / 6.0 m/s²

t = (42 m/s) / (6.0 m/s²)

t = 7 s
