A particle is going with constant speed along a uniform helical and spiral path separately as shown in figure

AThe velocity of the particle is constant in both cases

BThe magnitude of acceleration of the particle is constant in both cases

CThe magnitude of accleration is constant in $(a)$ and decreasing in $(b)$

DThe magnitude of accleration is decreasing continuously in both the cases

Solution

${a_c}\, = \,\frac{{{v^2}}}{r},$ radius is constant in case $(a)$ and increase in case $(b).$ So that magnitude of acceleration is constant in case $(a)$ and decrease in case $(b).$

A cyclist is riding with a speed of $27 \;km/h.$ As he approaches a circular turn on the road of radius $80\; m$, he applies brakes and reduces his speed at the constant rate of $0.50\; m/s$ every second. What is the magnitude and direction of the net acceleration of the cyclist on the circular turn ?

An object is moving on a circular track of radius $450\, m$. At some instant, the object is moving at $30\, m/s$ and gaining speed at a uniform rate of $2 m/s^2$. Its acceleration at this instant is nearly ………. $m/s^2$

medium

A uniform circular disc of radius $50\, cm$ at rest is free to turn about an axis which is perpendicular to its plane and passes through its centre. It is subjected to a torque which produces a constant angular acceleration of $2.0\, rad \,s^{-2}$. Its net acceleration in $ms^{-2}$ at the end of $2.0\,s$ is approximately
