In space, Asteroid A, called Dimorphos travels at constant speed in a circle around a larger Asteroid B, called Didymos. The diagram shows Asteroid A at position P. The distance $ r_{0} $ between Asteroid A and Asteroid B is 1.19 km. The time $ T_{0} $ for Asteroid A to travel on…

A student is investigating the motion of small metal balls falling from rest vertically through a liquid. The student drops a ball of diameter d from rest at the surface of the liquid. The student determines the terminal velocity v of the ball in the liquid. It is suggested that…

Fig. 4.1 shows a uniform wooden cylinder. Fig. 4.1 The cylinder has height 12.0 cm and diameter 2.9 cm. The density of the wood is $ 400 \, kg \, m^{-3} $. (a) (i) Show that the cross-sectional area of the wooden cylinder is about $ 6.6 \times 10^{-4} \, m^{2} $. [1] (ii) Calcula…
