B The weight of the coin equals the air resistance. C The weight of the coin increases as the air resistance increases. D The weight of the coin is always more than the air resistance. 3

3 The diagram shows the speed–time graphs for two objects moving with uniform acceleration. 0 0 6.0 4.0 speed m / s time / s object P 0 0 10.0 5.0 speed m / s time / s object Q A student uses the graphs to make two conclusions. 1 The distance travelled by object P is 26 m less than the distance travelled by object Q. 2 The acceleration of object P is 0.50 m / s 2 less than the acceleration of object Q. Which conclusions are correct? A neither 1 nor 2 B 1 only C 2 only D both 1 and 2

4 The diagram shows the load–extension graph for a spring. load extension 0 0 X What is the name given to point X on the graph? A limit of force B limit of proportionality C limit of the extension D limit of the spring

5 The diagram shows an athlete doing press-ups on a floor. The athlete is using both hands. The area of contact of each hand with the floor is S . The athlete’s toes act as a pivot during each press-up. S W point X toes The athlete’s weight W acts through point X. The distance between his toes and point X is three quarters of the distance between his toes and his shoulders. What is the pressure exerted on the palm of each of the athlete’s hands? A S W 8 B S W 8 3 C S W 4 D S W 4 3
