A 5 kg colloar is attached to a sprinig of spring constatn 500`Nm^(-1)` . It slides without friction over a horizontal rod. The collar is displaced from its equilibrium position by oscillations (b) The maximum speed and © maximum acceleration of the collar. |

Answer» Here, `m=5kg, k=500Nm^(-1)`, `a=10cm=0.10m` (a) `T=2pisqrt((m)/(k))=2pisqrt((5)/(500))=(2pi)/(10)s=0.628s` (b) `omega=(2pi)/(T)=(2pi)/((2pi//10))=10s^(-1)` Maximum velocity `=omegaa=10xx0.10` `=1ms^(-1)` (c) Maximum acceleration `=omega^(2)a` `=(10)^(2)xx0.1=10ms^(-2)` |
