Question
Q16: A rocket drifts sideways in outer space from point A to point B as shown below. The rocket is subject to no external forces. Starting at position B, the rocket's engine is turned on and produces a constant thrust (force on the rocket) at right angles to the line AB. The constant thrust is maintained until the rocket reaches a point C in space. As the rocket moves from position B to position C its speed is: constant for a while and decreasing thereafter. continuously decreasing. constant. increasing for a while and constant thereafter. continuously increasingExplanation / Answer
Q.16
Answer: Continuously incearing.
As the rocket has a constant thrust or Force, that means it will experience a constant acceleration equal to Force/Mass of rocket, and thus the velocity will be continuously inscreasing.
Q.05,
Answer: The acceleration is Zero
As the spider reaches center of the platform, its tangential velocity(vt = r.w) becomes zero, because r=0 at center, and therefore the centrifugal acceleration(vt2/r) also becomes zero, and therefore the acceleration will be zero.
