A particle moves on the $$x-$$ axis. When the particle's acceleration is positive and increasing then

A scooterist travels at 30 km/h along straight path for 20 min. What is distance?

Particle is dropped from the height of 20m on horizontal ground. There is wind blowing due to which horizontal acceleration of the particle becomes 6m$${ s }^{ -2 }$$. Find the horizontal displacement of the particle till it reaches ground. 

A ball is dropped downwards. After 2 second another ball is dropped downwards from the same point. What is the distance between them after 3 second?

A particle moves for $$8\ s$$. It first accelerates from rest and then retards to rest. If the retardation be $$3$$ times the acceleration, then the time for which it accelerates will be 

A bullet initially moving with a velocity $$20ms^{-1}$$ strikes a target and comes to rest after penetrating a distance $$10 cm $$ in the target .Calculate the retardation caused by the target. 

A train starting from a railway station and moving with uniform acceleration, attain a speed of $$40km {h^{- 1}}$$ in $$10$$ minutes. Its acceleration is:

The average speed of an object is defined to be

What determine the nature of the path followed by the particle 

A body starts from the rest with uniform acceleration. If its displacement in the 3rd seconds and 7th second are $$x_1$$ and $$x_2$$, then:
