Rockets have been developed so that people who are not trained astronauts can pay to travel to space. Figure 9 shows the passenger module and the propulsion module of a rocket. The propulsion module burns a large volume of fuel. Figure 9 1 The rocket was initially stationary on t…

A car contains a device called a black box. The black box records the velocity and acceleration of the car. The car was travelling at a constant velocity. The driver then reacted to a hazard. Figure 11 shows the velocity-time graph for the car. Figure 11 1 Determine the decelerat…

Figure 11 shows a stationary apple hanging from a tree. The X marks the centre of mass of the apple. Figure 11 2 It takes 0.50 s for the apple to fall to the ground. The initial velocity of the apple is 0 m/s acceleration due to gravity = 9.8 m/s $ ^{2} $ Calculate the distance f…
