Assuming an object has a total mass of M and gravitational constant on earth = g, air resistance = Cd, total surface area = A, initial height = H, and this object has a thruster (assuming constant thrust = F_thrust) that ignites at a time T_ignition and stops burning at time T_turnoff (T_turnoff and T_ignition occur at different time during the process), please derive an equation for the velocity of this linear vertical motion as a function of time, V(t).

A 2400-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=At+Bt2, where A and B are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 1.90 m/s2 and 1.20 s later an upward velocity of 1.50 m/s . Part A) Determine A....

Two objects are dropped from the same height on earth. One has a mass three times greater than the other one. If they are dropped at the same time, assuming no air resistance, which of the following statements is true? The acceleration is the same for both objects, but the force on the lighter object is greater. The lighter object experiences one-third the force of the heavier object, but the acceleration of the two objects are the same. The lighter...

An object of mass m = 0.25 kg has a horizontal spring attached to its left side, and slides along a frictionless surface. The spring constant is κ = 0.4 N m . At t = 0 s, the object is displaced 0.1m to the right of its equilibrium position. Its initial velocity is 0.4 m s , toward the right. a) Calculate the period T of the motion. b) Calculate the angular frequency ω. c) Calculate the frequency ν....

Speed means the absolute value of the velocity, hence it is always non-negative. While the sign of the velocity indicates the direction of the motion, the speed is insensitive to the direction. For example, speed is the value displayed by car’s speedometer; it does not indicate the direction of driving (e.g., northbound versus southbound). At time t = 0 seconds (s) an object has zero velocity and it starts a free fall from the altitude of 1200 metres (m) above...
