The odometer of a car reads $$57321.0 km$$ when the clock shows the time $$08:30$$ AM. What is the distance moved by the car, if at $$08:50 AM$$, the odometer reading has changed to $$57336.0 km$$?

The velocity of the object over the interval (2,4) is :

The acceleration due to gravity on the planet A is 9 times the acceleration due to gravity on the planet B. A man jumps to a height of 2m on the surface A. What is the height of jump by the same person on the plane B?

An object is thrown vertically upward with a speed of $$30m/s$$. The velocity of the object half a second before it reaches the maximum height is

Two cars started moving with initial velocities $$u$$ and $$2u$$. For the same deceleration, their respective stopping distances are in the ratio

A body of mass $$2kg$$ has an initial velocity of $$3m/s$$ along $$OE$$ and it is subjected to a force of $$4N$$ along of direction perpendicular to $$OE$$ as shown in figure. The distance travelled by the body in $$4s$$ from $$O$$ will be

A car starts moving along a line, first with an acceleration $$a = 5\ ms^{-2}$$ starting from rest, then uniformly and finally decelerating at the same rate, comes to rest in the total time of $$25\ seconds (t_{1})$$, then average velocity during the time is equal to $$v = 72\  kmph$$. How long does the particle move uniformly?

In the following displacement (x) vs time (t) graph, at which among the points P, Q and R is the object's speed increasing?

A bullet moving with a speed of $$150$$ $$ms^{-1}$$, strikes a wooden plank. After passing through the plank, its speed becomes $$125$$ $$ms^{-1}$$. Another bullet of the same mass and size strikes the plank with a speed of $$90$$ $$ms^{-1}$$. Its speed after passing through the plank would be.
