Two rockets are flying in the same direction and are side by side at the instant

Two rockets are flying in the same direction and are side by side at the instant their retrorockets fire. rocket a has an initial velocity of +6500 m/s, while rocket b has an initial velocity of +8700 m/s. after a time t both rockets are again side by side, the displacement of each being zero. the acceleration of rocket a is -13 m/s2. what is the acceleration of rocket b?

The acceleration of rocket B is -17.4 m/s².

Explanation:

Given that,

Initial velocity of rocket A = 6500 m/s

Final velocity of rocket B = 8700 m/s

Acceleration of rocket A = -13 m/s²

Displacement of both rocket is zero.

We need to calculate the time of rocket A

Using equation of motion

S_{A}=ut+\dfrac{1}{2}at^2

Put the value into the formula

0=6500t+\dfrac{1}{2}\times(-13)\times t^2

t=1000\ sec

We need to calculate the acceleration of rocket B

Using equation of motion

S_{B}=ut+\dfrac{1}{2}at^2

Put the value in the formula

0=8700\times1000+\dfrac{1}{2}\times a\times(1000)^2

a=\dfrac{8700\times1000\times2}{(1000)^2}

a=-17.4\ m/s^2

Hence, The acceleration of rocket B is -17.4 m/s².

When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.
