The track for a motorbike race consists of a straight, horizontal section that is 800 m long. A participant, such as the one in the picture above, rides at a certain average speed and completes the 800 m course in 75 s. To maintain this speed, a constant driving force of 240 N acts on … Read more
A bullet of mass 20 g is fired from a stationary rifle of mass 3 kg. Assume that thebullet moves horizontally. Immediately after firing, the rifle recoils (moves back) with avelocity of 1,4 m∙s-1. 4.1 Calculate the speed at which the bullet leaves the rifle. (4) The bullet strikes a stationary 5 kg wooden block … Read more
Ball A is projected vertically upwards at a velocity of 16 m∙s-1 from the ground. Ignore the effects of air resistance. Use the ground as zero reference. 3.1 Calculate the time taken by ball A to return to the ground. (4) 3.2 Sketch a velocity-time graph for ball A. Show the following on the graph: … Read more
2.1 Two blocks of mass M kg and 2,5 kg respectively are connected by a light, inextensible string. The string runs over a light, frictionless pulley, as shown in the diagram below. The blocks are stationary. 2.1.1 State Newton’s THIRD law in words. (2) 2.1.2 Calculate the tension in the string. (3) The coefficient of … Read more

An experiment is done to verify that the potential difference across a conductor is directly proportional to the current in the conductor if the temperature stays constant. Four cells, each with an emf of 1,5 V, are connected in series with an ammeter, switch S and a combination of a resistor R and resistors of … Read more
A circular coil with 250 windings (turns) and a radius of 0,04 m, is rotated clockwise inside a magnetic field with a field strength of 3,2 T. 9.1 Calculate the magnetic flux through the coil at the position indicated on the diagram, where the coil is perpendicular to the field. (3) 9.2 If the coil … Read more
Two charged spheres, X and Y, are placed in a vacuum at a distance of 0,04 m apart. 8.1 Draw the resulting electric field pattern between the two charges. (3) 8.2 Calculate the electrostatic force sphere X experiences due to the charge on sphere Y. (4) 8.3.1 If sphere Y is at a fixed position … Read more
