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

Put the value into the formula

We need to calculate the acceleration of rocket B

Using equation of motion

Put the value in the formula

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

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
