If there is no air resistance, which statement about the acceleration of the ball is wrong? It always acts towards the centre of the Earth. It is zero when the ball is at the highest point. It has the opposite sign to its velocity when the ball is moving upwards. It maintains the same value throughout its motion. 2 / 5 2) 2018 S4 EOY P1 Q05 A ball is thrown vertically upwards at a velocity of 12 m s-1. The ball rises to the highest point. Which of the following statements is false for the ball at this point? The time taken to rise to this point is 1.2 s. The ball has travelled a distance of 14.4 m. The magnitude of the acceleration of the ball is 10 m s-2. The velocity of the ball is 0 m s-1. 3 / 5 3) 2022 S4 MY P1 Q02 A girl throws a ball vertically upwards at 20 m s–1 such that it hits a ledge 15.0 m above her hand. Assume air resistance is negligible. How long was the ball in the air? 1.5 s 3.0 s 1.0 s 0.75 s 4 / 5 4) A man standing on the balcony of his house throws a ball vertically upwards. The ball reaches the maximum height after 2.0 s before dropping to the ground below. Take the upward direction as positive and assume air resistance is negligible. Which of the following statements about the motion of the ball is incorrect? The velocity at the maximum height is 0 m s-1. The acceleration throughout the motion is –10 m s-2. The ball left the hand at a velocity of 20 m s-1. The ball will hit the ground at a velocity of –20 m s-1. 5 / 5 5) 2012 S3 BT2 Q02 The diagram below shows a strip of paper tape that has been pulled under the vibrating arm of a ticker timer by an object travelling at steady speed. The vibrating arm of the ticker timer is vibrating regularly, making 50 dots per second. What was the speed of the object? 45 cm s–1 0.91 cm s–1 50 cm s–1 1.0 cm s–1 Your score is Restart quiz
