A particle of mass

m \mathrm{~kg}

is travelling at constant speed

v \mathrm{~m} / \mathrm{s}

round a circle of radius

r_{m^{\prime}}

(a) If

v=8

and

r=2

, find the magnitude of the central acceleration (in

\mathrm{m} / \mathrm{s}^2

).

View answer and explanation

Correct option: A

32

Option A (32) is correct because the centripetal acceleration is calculated using

a = v^2/r

, where v is the speed and r is the radius.

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
