(a) Explanation Given Info : The mass of rocket is 3.00 × 10 5 kg , acceleration is 36.0 m / s 2 and the speed of exhausted gases is 4.50 × 10 3 m / s . The rate at which the fuel burns initially is given by the ratio | Δ M Δ t | . Write the formula to calculate the rate of initial fuel burning of rocket. M a = | v e Δ M Δ t | M is the mass of rocket a is the acceleration of rocket v e is the speed of exhausted gases Δ M is the change in mass of rocket Δ t is the time interval for change in mass Rewrite the above equation in terms of | Δ M Δ t | . Substitute 3.00 × 10 5 kg for M , 36 (b) To determine The rate of fuel burning if the rocket is vertically launched from the Earth’s surface with the same initial velocity.

Central Force

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force betwe…

Two resistors of resistances R1 and R2, with R2>R1, are connected to a voltage source with voltage V0. When the resistors are connected in series, the current is Is. When the resistors are connected in parallel, the current Ip from the source is equal to 10Is. Let r be the ratio R1/R2. Find r. I know you have to find the equations for V for both situations and relate them, I'm just struggling to do so. Please explain all steps, thank you.

Bheem and Ram, jump off either side of a bridge while holding opposite ends of a rope and swing back and forth under the bridge to save a child while avoiding a fire. Looking at the swing of just Bheem, we can approximate him as a simple pendulum with a period of motion of 5.59 s. How long is the pendulum ? When Bheem swings, he goes a full distance, from side to side, of 10.2 m. What is his maximum velocity? What is his maximum acceleration?

The position of a 0.300 kg object attached to a spring is described by x=0.271 m ⋅ cos(0.512π⋅rad/s ⋅t) (Assume t is in seconds.) Find the amplitude of the motion. Find the spring constant. Find the position of the object at t = 0.324 s. Find the object's velocity at t = 0.324 s.
