The motion of a particle is given by x = A sincot + costa. The motion of the particle is

Is it 56m or 16m? And whichever the choice may be, but how do you decide it?

(i) Motion of your hands while running – Oscillatory motion. (ii) Motion of a horse pulling a cart on a straight road – Straight line motion. (iii) Motion of a child in...

(i) The motion of a swing is an example of periodic motion.                                           or The motion of a swing is not an example of rectilinear motion. (ii) 1m = 100 cm

(a) As x increases k increases.  Explanation: Since the motion is simple harmonic, the force F=-⍵²x where ⍵² is a constant. Equating the force applied by the student we get, -k/x=-⍵²x  →k=⍵²x²  It is...

(c) on a circle

The correct answer is (b) B EXPLANATION: The equation can be written as x-A=B.sin⍵t If x-A=y then y=B.sin⍵t This is the equation of a simple harmonic motion with amplitude B. Hence option(b). 

(b)  The original point then t1 > t2. Explanation: Since F is in the direction of particle's motion it will add an acceleration in the direction of motion. Let it be a. Now magnitude...

(d) simple harmonic with amplitude √(A2 + B2).

(c) Managua is the capital of Nicaragua, not Balmopan. Balmopan is the capital city of Balize.

No. Generally rotational motion is a periodic motion. Periodic motion is a motion that repeats itself at regular time intervals. Rotational motion is a type of periodic motion. For example, the...
