A river of width 100 m is flowing north at 5 m/s. A motor boat that can travel at 3 m/s in still water is crossing the river from the west bank to the east bank. What is the smallest distance down the river (measured along the shore) that the boat can land on the eastern shore?

A 3D scan is taken with a terrestrial laser scanner. The precision of the range measurement is stated to be ±(2 mm + 5 ppm). IF the scanner measures 457.251 m to an object in the scene. Giving your answer to the nearest 0.1 millimetre and using units of millimetre, what is the precision of this measurement?

Five engineers measure the thickness of a slab using a meter stick and a vernier caliper. One engineer got a thickness of 4.3 cm ± 0.1 cm using a meter stick, the other four engineers measured a thickness of (a) 4.32 cm ± 0.01 cm, (b) 4.31 cm ± 0.01 cm, (c) 4.24 cm ± 0.01 cm, and (d) 4.43 cm ± 0.01 cm respectively using the caliper. Which of these four measurements made by the four engineers agree with the measurement obtained by the engineer that used a meter stick? Choose the correct answer. Only a (b) and (c) (c) and (d) (a), (b), and (c) none of these Two cannonballs were fired at the same speed. If the cannonball 2 has a mass that is twice the mass of cannonball 1, what is the kinetic energy of cannon ball 2? (Assume that the kinetic energy of cannon ball 1 is equal to K) Choose the correct answer. 25K 5K 71K K 2K
