Question 8 :
A 1,000 kg vehicle moving with a speed of $20\ ms^{-1}$ is brought to rest in a distance of 50 m. Find the acceleration.<br/>
Question 9 :
A body of mass 225 kg is moving with a velocity of 20 m/s. If the velocity-time graph for this body is a horizontal line parallel to the time axis, then the velocity of the body after 28s will be
Question 11 :
The roadway bridge over a canal is in the form of an arc of a circle of radius $20\ m$. What is the maximum speed with which a car can cross the bridge without leaving the ground at the highest point.
Question 12 :
A car starts from rest and accelerates uniformly over a time of $5.21$ seconds for a distance of $110$ m. Determine the acceleration of the car.<br/>
Question 13 :
The velocity acquired by a body when it falls through $a$ height $h$ is $v$. If it further falls through a height  $x$ $ (x << h)$ , the increase in velocity is approximately
Question 14 :
A ball is thrown from the top of a tower in vertically upward direction. Velocity at a point h metre below the point of projection is twice of the velocity at a point h metre above the point of projection. Find the maximum height reached by the ball above the top of tower.
Question 15 :
A body falls freely from the top of a tower. It covers $36\%$ of the total height in the last second before striking the ground level. The height of the tower is<br>
Question 16 :
In the above question , the time after which the centres of gravity of the two bodies will have a separation $h$, is<br/>
Question 17 :
A particle is moving with uniform acceleration along a straight line ABC. Its velocity at 'A' and 'B' are 6m/s and 9m/s respectively. AB:BC=5:16 then its velocity at 'C' is
Question 18 :
A particle is projected from ground with initial speed $u$ at angle $\theta$ with horizontal. If air friction is absent, then the average velocity of complete motion will be:
Question 19 :
A plane has a takeoff speed of $88.3 m/s$ and requires $1365 m$ to reach that speed. Determine the time required to reach this speed.
Question 20 :
Assertion: Acceleration of a moving particle can change it's direction without any change in direction of velocity.
Reason: If the direction of change in velocity vector changes, the direction of acceleration vector also changes.
