Q. Far in space, where gravity is negligible, a 480-kg rocket travelling at 95 m/s fires its engines. The figure shows the thrust force as a function of time. The mass lost by the rocket all through these 30s is negligible.
At what time does the rocket reach its highest speed?
What is the highest speed of rocket?
What was the initial speed of the arrow. A block with mass m = 19.7 kg slides down an inclined plane of slope angle 35.8 deg with a constant velocity. It is then projected up the similar plane with an initial speed 1.05 m/s. How far up the incline w..
A long straight metal wire of radius r1= 3.30E-2 m is bounded by a metalic cylindrical shell of inner radius r2= 1.39 E-1 m and outer radius r3= 1.84E-1 m.
Find out the minimum horizontal velocity magnitude of the acceleration of the blocks
What is the least (non-zero) thickness for the air layer between two flat, and parallel, glass surfaces if the glass is to appear dark while 640 nm light is incident normally? What if the glass is to appear bright.
An air puck of mass 0.029 kg is tied to the string and allowed to revolve in a circle of radius 2.0m on a frictionless horizontal surface. The other end of the string passes through a hole in the center of surface, and a mass of 2.6 kg is tied to it...
Assuming that the total retarding force on the diver is constant at 55.0 N with the parachute closed and constant at 3600 N with the parachute open, what is speed of the diver while he lands on the ground.
Discuss the cause and different mechanisms available. Recognize and discuss the flow control techniques on which they are based? Determine the pros and cons of each?
A ladder of unknown length and mass of 29.00 kg rests on a rough floor, and leans against a rough wall. The coefficient of static friction between the ladder and both the floor and wall are 0.68.
An insulated Thermos contains 131 cm3 of hot coffee at 82 °C. You put a 12g ice cube at its melting point to cool the coffee. By how many degrees has the coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though ..
Suppose that the speed of the water in the reservoir is zero, and that the water flow is steady. Overlook both air resistance and the height difference between the reservoir and the muzzle.
find the maximum distance she can be from the craft and still return within 2.30 min (the amount of time the air in her helmet remains breathable).
A friend of yours is loudly singing a single note at 400 Hz as driving toward you at 250 m/s on a day when the speed of sound is 340 m/s
