ASSESSOR....... MODERATOR . CPH/MEP FINAL 2020 Question 11 A block is released from the top of a smooth inclined plane. Another block of the same mass is allowed to fall freely from the top of the inclined plane. Both blocks reach the bottom of the plane . Question 12 A body of mass m is resting on the floor. A minimum amount of force is applied on the body and the force continues to act on the body as it moves. If the coefficient of static and dynamic friction are 0.4 and 0.3 respectively, then the acceleration of the body is Question 13 An object of mass 100kg is accelerated uniformly from a velocity of 4 m/s to 8 m/s in 2 seconds. Calculate the initial and final momentum of the object Question 14 An airplane is flying in a horizontal direction with a velocity 600 kmh-1 at a height of 1960 m. When it is vertically above the point A on the ground, a body is dropped from it The body strikes the ground at point B. Calculate the distance AB B Question 15 The image formed by a concave lens is Question 16 If the angle of incidence, Đi = 0°, the angle of reflection, 8r =, Question 17 The force between two charges is 120 N. If the distance between the charges is doubled, the force will be ASSESSOR.. MODERATOR . СРН/МЕP EINAI 2020
