Forces 5 N, 12 N and 13 N are in equilibrium. If $ sin\text{ }23{}^\circ =\frac{5}{13}, $ the angle between 5 N force and 13 N force is
A particle is moving along a circular path of radius $5 \,m $ with a uniform speed $5\, ms^{ - 1 } $ What will be the average acceleration when the particle completes half revolution ?
A particle is thrown vertically upwards. Its velocity at half of the height is $ 10\, ms^{ - 1} $ . Then the maximum height attained by it is (Take $g = 10\,ms^{ -2} $ )
A body moves along a circular path of radius $10\, m$ and the coefficient of friction is $0.5$. What should be its angular speed in rad/s if it is not to slip from the surface? ( $ g=9.8\text{ }m{{s}^{-2}} $ )
A $100\, m$ long train is moving with a uniform velocity of $45\, km/h$. The time taken by the train to cross a bridge of length $1\, km$ is:
A wet open umbrella is held vertical and it whirled about the handle at a uniform rate of $21$ revolutions in $44\, s$. If the rim of the umbrella is a circle of $1\, m$ in diameter and the height of the rim above the flour is $4.9\, m$, the locus of the drop is a circle of radius:
