We were made aware of certain amendments and omissions that were discovered during the marking process and memorandum discussion on the provided marking guideline. In order to address this and to ensure that learners are not disadvantaged, the following standardised approach to marking must be adopted across the Province. The following guidelines regarding marking was prepared in conjunction with the examiner and moderator. QUESTION 1 1.6. C  QUESTION 2 2.1. The force that opposes the motion of a moving object relative to the surface .. (2 or 0) 2.3.1. fk = μ k N any one . fk = μk (mg – Fsinθ) fk = [0,2 x( 20 x 9,8 - 105sin25o )] . fk = 30,33 N left . Page 1 of 2 Provincial Examination Errata

EQUAL TO.  Newston’s law 3.  OR When object A exerts a force on object B, object B simultaneously exerts an oppositely directed force on object A of equal magnitude. 3.4. Fnet = ma  [(4 x14,98) = 1500a]  a = 3,99 x 10-2 m.s-2  QUESTION 4 4.1. The motion of an object upon which the only force acting is gravitational force.  4.2.2. Positive Marking from 4.2.2. 4.2.4. Same (initial) velocity . They are undergoing Free fall motion OR same gravitational acceleration . QUESTION 5 5.3.1 Typing error: m1vi1 + m2vi2 = (m1 + m2) vf  Positive Marking from 5.3.1 5.4. Ektotal = ½ (mvi2 + mvf2) Ektotal = ½ (mvi2 + mvf2)  Eki = ½ x 1 500 x 202 + 0  Eki = 300 000 J Ekf = ½ x 1 500 x 12,52 + ½ x 900 x 12,52  Ekf = 187 500 J Eki ≠ Ekf  Inelastic collision.  5.5. The buble wrap provides soft surface  which increases the contact time of the collision  and decreases the net force exerted on the equipment.  OR Net force is inversely proportional to the contact time.  Page 2 of 5 Provincial Examination Errata
