Question Answer Marks Guidance 21 (a) distance = area under the graph/suvat equations ½ (4.0 + 10.0) 3.0 / 10.0 5.0 horizontal distance = 71 (m) C1 C1 A1 Allow any attempt to calculat... e part of the area under the graph or suvat equations Allow any correct calculation of part of the area under the graph/suvat eqn e.g. 9, 12, 20, 21, 30, 32, 50 (m) (b) (i) a = 6.0 3.0 2.0 C1 A0 Allow any correct gradient calculation (ii) 680cos55 / 150 2.0 680cos55 – R = 150 2.0 R = 90 (N) C1 C1 A1 If both components given (vertical and horizontal) it must be clear that the 390N is the horizontal component. Total 7 H156/01 Mark Scheme June 2022 10 Question Answer Marks Guidance 22 (a) Add (a range of) loads/force/weights to the spring and determine the compression (for each load) Plot a graph for force against compression and gradient is the force constant B1 B1 Allow extension for compression throughout Allow W = mg Not length for compression Allow force constant = force compression and k = F/x (k must be subject) (b) KE/kinetic to gravitational PE/potential B1 Allow KE transferred to GPE Ignore increase of thermal store of the surroundings Not elastic potential energy (c) E = ½ 1.7 104 (0.45 – 0.25)2 E = 340 (J) C1 A1 Allow gain in GPE = 68g(0.76 – 0.25) Ignore E = ½ Fx (d) The gravitational potential energy store of the person has been omitted/(elastic) potential store of the spring has been transferred to gravitational potential energy store (of the person) B1 Ignore references to energy losses [Show More]
