Question:

A particle moves such that its vector is given by π‘Ÿ

= cos πœ”π‘‘π‘– + sin πœ”π‘‘π‘— where πœ” is a constant. Show that:

(i)

Velocity, 𝑣

of the particle is perpendicular to π‘Ÿ


(ii)

Acceleration, π‘Ž

is directed towards the origin and has magnitude proportional to the

distance from the origin.

(iii) π‘Ÿ

𝑋 𝑣

is a constant vector


Question:

If π‘Ž and 𝑏 are two sides of a right angled hypotenuse 𝑐 and let 𝑝 be the perpendicular from the opposite

vertex on the hypotenuse, show that:
