A block is projected up a rough inclined plane with an initial velocity $u$. The coefficient of kinetic friction between the block and the plane is $\mu_k$. The block travels a distance $s$ up the plane before coming to rest. What is the angle of inclination $heta$ of the plane?

A block of mass 5 kg is placed on a horizontal surface. The coefficient of static friction between the block and the surface is 0.4. What is the maximum horizontal force that can be applied to the block before it starts to slide?

Which process is NOT associated with asexual reproduction?

In which of the following cases forces may not be required to keep the

If the force applied to a stationary object is doubled, and the object still doesn't move, what happens to the static friction force acting on the object?

Two blocks of masses $m_1$ and $m_2$ are connected by a massless string passing over a smooth pulley. The coefficient of kinetic friction between $m_1$ and the horizontal surface is $\mu_k$. If $m_2$ is descending with a constant acceleration $a$, what is the tension in the string?

A body of mass M at rest explodes into three pieces, two of which of mass M/4 each are thrown off in mutually perpendicular directions with speeds of 3${\rm{ms}}{{\rm{\;}}^{ - 1}}$ and 4${\rm{ms}}{{\rm{\;}}^{ - 1}}$ respectively. Then the third piece will be thrown off with a speed of

Consider two blocks A and B connected by a light string passing over a frictionless pulley. Block A (mass 4 kg) rests on a horizontal surface with a coefficient of kinetic friction 0.3, while block B (mass 3 kg) hangs vertically. Find the acceleration of the system. (Take g = 9.8 m/s²).

A block is placed on an inclined plane of angle $heta$. The coefficient of static friction between the block and the plane is $\mu_s$. What is the maximum angle of inclination $heta$ for which the block will remain at rest?

A body at rest explodes into two equal parts. Then,

A shell is fired from a cannon with velocity v m/sec at an angle θ with the horizontal direction. At the highest point in its path it explodes into two pieces of equal mass. One of the pieces retraces its path to the cannon and the speed in m/sec of the other piece immediately after the explosion is
