11. A force of 10 N produces an acccleration of 2ms in a body. Calculate the mass of the body12. A ball of mass 200 g moving with an acceleration of 3ms strikes a wall. What is the force esened by the wallion the ball?cal mantity makes it easier to move a car than to move a truck?

Answer»

Force=mass*accelerationmass=10/2=5kg

Question 11 Force=mass×acceleration 10 =mass×2mass = 10/2 =5 kg ans

Question 12 mass of ball =200g=0.2kgacceleration = 3m/s*s Force = mass × acceleration = 0.2*3 = 0.6N ans
