Explain the following:
$(i)$ Why do we jerk wet clothes before spreading them on a line?
$(ii)$ Why does dust fly off when a carpet is hit with a stick?
$(iii)$ Why do fruits fall off the branches in a strong wind?
$(iv)$ Why does a pillion rider fall forward when the driver of a two-wheeler suddenly applies brakes?

(N/A) $(i)$ Initially,both water and clothes are at rest. When wet clothes are jerked,the water particles tend to remain in their state of rest due to the inertia of rest. This causes the water droplets to detach from the clothes,helping them dry faster.
$(ii)$ When a carpet is struck with a stick,the carpet moves suddenly,but the dust particles tend to remain at rest due to the inertia of rest. Consequently,the dust separates from the carpet and flies off.
$(iii)$ Initially,the fruits on the branches are at rest. Due to the inertia of rest,the fruits tend to remain in their state of rest even when the branches are moved by a strong wind,causing the fruits to detach and fall.
$(iv)$ Initially,both the driver and the pillion rider are in a state of motion. When the driver applies brakes,the lower part of the pillion rider's body comes to rest with the vehicle,but the upper part continues to move forward due to the inertia of motion,causing the rider to fall forward.
