NCERT solutions for class 11 physics chapter 5 laws of motion – This chapter covers selected problems from the chapter laws of motion. Here we are solving selected problems both from Exemplar and NCERT Physics textbook. If any problem needs some coverage of fundamentals we are catering that also. We are giving the reference to
Problem Statement A bullet of mass 50 g moving with an initial velocity of 100 m/s, strikes a wooden block and comes to rest after penetrating a distance 2 cm in it. Calculate: (i) Initial momentum of the bullet (ii)final momentum of the bullet (iii) retardation caused by the wooden block, and (iv) resistive force
Problem statement A force causes an acceleration of 10 m/s^2 in a body of mass 500 g. What acceleration would be caused by the same force in a body of mass 5 kg. Solution Case 1 mass = m=500 g = 0.5 kg Acceleration = a =10 m/s^2 Force = ma = 0.5 . 10
Problem Statement A body of mass 500 g, initially at rest, is acted upon by a force which causes it to move a distance of 4 m in 2 sec. Calculate the force applied. mass=m = 500 g = 0.5 kg Initial velocity = u = 0 Distance travelled = s=4 m Time duration =t=
