Two rockets are flying in the same direction and are side by side at the instant their retrorockets fire. Rocket A has an initia

lara31 [8.8K]

Answer:

-22.2 m/s²

Explanation:

The equation for position x for a constant acceleration a, time t and initial velocity v₀, initial position x₀:

(1) $x=\frac{1}{2}at^2+v_0t+x_0$

For rocket A the initial and final position: x = x₀= 0. Using these values in equation 1 gives:

(2) $0=\frac{1}{2}at^2+v_0t$

Solving for time t:

$-\frac{1}{2}at^2=v_0t$

(3) $t=-\frac{2v_0}{a}$

The times for both rockets must be equal, since they start and end at the same location. Using equation 3 for rocket A and B gives:

(4) $\frac{v_{0A}}{a_A}=\frac{v_{0B}}{a_B}$

Solving equation 4 for acceleration of rocket B:

(5) $a_B=a_A\frac{v_{0B}}{v_{0A}}$

What did isaac Newton believe light was made of

adelina 88 [10]

Sir Isaac Newton, held the theory that light was made up of tiny particles. In 1678, Dutch physicist, Christiaan Huygens, believed that light was made up of wavesvibrating up and down perpendicular to the direction of the light travels, and therefore formulated a way of visualising wave propagation.

Complete Question

The complete question is shown on the

Answer:

The ascending order would be 2nd < 1st < 3rd

Explanation:

Generally the the Normal force is mathematically represented as

$Normal \ Force = Fsin \theta$

=> $Normal \ Force \ \alpha \ sin \theta$

For the first drawing the value $\theta$ is between that of the the second and the third drawing so the Normal force would also be between the normal forces of the second and the third drawing

For the second drawing whose value of $\theta$ is less than that of the first and the third the normal force would also be less than that of the first and third

For the the third drawing whose value is (90°) which is higher than the first and the second the normal force would also be higher than the first and the second
