Question Text
Question 2 :
If a particle moves in a closed path with a constant speed of 10 m/s, we can always say, that there will be a change in velocity. 
Question 3 :
If a trolley starts from rest with an acceleration of 2 $m/s^2$, the velocityof the body after 4 s would be
Question 4 :
A ball starts rolling on a horizontal surface with an initial velocity of 1 m/s. Due to friction, itsvelocity decreases at the rate of ${0.1 m/s^2}$ , Howmuch time will it take for the ball to stop?
Question 5 :
A block of mass 2 kg falls from the wall at height of 2.3 m. Calculate the velocity just before it hits the ground. ($g=-9.8 \frac{m}{s^2}$)<br/>
Question 6 :
A ball is thrown upward with an initial velocity of $\displaystyle 100\ ms^{-1}.$ After how much time will it return to the ground.
Question 7 :
A particle starts from rest with constant acceleration for $20$ sec. If it travels a distance $y_1$ in the first $10$ sec and a distance $y_2$ in the next $10$ sec then?
