Give explanation. 3) It truly is advised to tie the baggage kept on the roof in the bus which has a rope. Give reason. 4) Give two examples to exhibit that better the mass greater the inertia. 5) Calculate the of a toy car weighing 200g and moving using a velocity of 5m/s. 6) What is the acceleration produced by a pressure of 12N exerted on an object of mass 3kg? 7) An auto weighing 1600kg moving which has a velocity of 30m/s retards uniformly visiting rest in 20s. Calculate the a) Initial momentum of the car
b) Final momentum with the car
c) Rate of change of momentum
d) Acceleration with the car
e) Magnitude of the force applied.
8) A cricket ball of mass 100g shifting with a acceleration of 30m/s is taken to rest with a player in 0. 03s. Find the change in momentum of the ball and the common force utilized by the player. 9) A 1000kg mass having a velocity of 10m/s is taken to rest more than a distance of 100m. Discover the reifungsverzogerung and slowing force. 10) A truck beginning from rest proceeds down a hill with a constant velocity. If it trips a range of 300m in 10s, find the acceleration. Discover the power acting on this if the mass is 8000kg. CHEMISTRY
