Motion in A Str...

An object is sliding down on an inclined plane. The velocity changes at a constant rate from 10 cm/s to 15 cm/s in 2 seconds. What is its acceleration?

Consider two observers moving with respect to each other at a speed $$v$$ along a straight line. They observe a block of mass $$m$$ moving a distance $$l$$ on a rough surface. The following quantities will be same as observed by the two observers.

If a car at rest accelerates uniformly to a speed of $$144\ km/h$$ in $$20$$ second, it covres a distance of :-

The unit for the rate of change of velocity is 

A body starts from rest is moving under a constant acceleration up to 20 s . If it moves $$S_{1}$$ Distance in first 10 s, and $$S_{2}$$ distance in next 10 s then $$S_{2}$$ will be equal to:

An aeroplane is flying in a horizontal direction at $$600 km/hr$$ at a height of $$6 kms$$ and is advancing towards a point which is exactly over a target on earth. At that instant the pilot releases a ball which on descending the earth strike the target. The falling ball appears-

A particle travels $$10\ m$$ in first $$5\ s$$, $$10\ m$$ in next $$3\ s$$. Assuming constant acceleration, what is the distance traveled in the next two seconds.

A body travels $$200\ cm$$ in the first two seconds and $$220\ cm$$ in the next $$4\ s$$ with same acceleration.The velocity of the body at the end of the $$7^{th}$$ second is 

A truck of mass $$2800 kg$$ is moving with a speed of $$15\:m/s$$. A frictional retarding force of $$1200 N$$ are acting on it, then in $$10 s$$ it shall travel a distance of:

The distance between them at time $$t$$ is:-
