An object moves (3.5x10^0) metres, stops, and them moves (3.340x10^0) Ý metres. What is the total displacement. Give your answer to 2 sf. In your answer, you do not enter the ġ unit vector, but you do need to enter negative signs, if appropriate. e.g. if your answer is a -3.19 metres, you would enter -3.1 metres Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10
An object is moving with an initial velocity of (2.900x10^0)m/s and a final velocity (7.1x10^0) ŷ m/s. The time taken for acceleration is (3.30x10^0) seconds. Calculate the acceleration in m/s2 to 2 sf. In your answer, you do not enter the ġ unit vector, but you do need to enter negative signs, if appropriate. e.g. if your answer is a = -2.99 m/s2, you would enter -2.9 Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: X10 NA
A thunderstorm is (1.100x10^0) km from your position. You see a flash of lightning, and (2.9x10^0) seconds later, you hear the sound of the thunder. What is the speed of sound, in m/s? Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: X10
