A particle of mass $m$ is constrained to move on $x$-axis. A force $F$ acts on the particle. $F$ always points toward the position labeled E. For example, when the particle is to the left of $E$, $F$ points to the right. The magnitude of $F$ is constant except at point $E$ where it is zero.
The system is horizontal. $F$ is the net force acting on the particle. The particle is displaced a distance A towards left from the equilibrium position $E$ and released from rest at $t=0$
Find minimum time it will take to reach from $x=-\frac{A}{2}$ to $0.$

A pebble of mass $0.05\; kg$ is thrown vertically upwards. Give the direction and magnitude of the net force on the pebble,
$(a)$ during its upward motion,
$(b)$ during its downward motion,
$(c)$ at the highest point where it is momentarily at rest.
Do your answers change if the pebble was thrown at an angle of $45^o$ with the horizontal direction? Ignore air resistance.
