Vedclass · Answer

(D) According to Newton's second law,the net force acting on the block is given by $F_{net} = ma$,where $m$ is the mass of the block and $a$ is its acceleration.Velocity is maximum when the acceleration of the object is zero,which implies that the net force acting on the object is also zero.In this system,the forces acting on the block are the spring force and the kinetic friction force. The block reaches its maximum velocity at the point where the spring force is exactly balanced by the frictional force,resulting in a net force of zero and consequently zero acceleration.

$A$ spring-block system is placed on a rough horizontal floor. The block is pulled towards the right to give the spring some elongation and then released. The block will have maximum velocity when:

$A$ force $F$ pulls a block of mass $60 \ kg$ at a constant speed across the floor. The coefficient of friction is $\mu = 1/3$. What is the magnitude of the force $F$ (in $N$)?

When the engine is switched off, a vehicle of mass $M$ is moving on a rough horizontal road with momentum $p$. If the coefficient of friction between the road and the tyres of the vehicle is $\mu_k$, what is the distance travelled by the vehicle before it comes to rest?

$A$ block of mass $M = 5\,kg$ is resting on a rough horizontal surface for which the coefficient of friction is $0.2$. When a force $F = 40\,N$ is applied at an angle of $30^\circ$ with the horizontal,the acceleration of the block will be ........ $m/s^2$ $(g = 10\,m/s^2)$.

What is the maximum force $F$ (in $N$) that can be applied such that the block does not move? (Given $\mu = 1/(2\sqrt{3})$ and $m = \sqrt{3} \ kg$)
