Question

Paul was very happy with his first race (described in Part A), but he only finished in second place. He decides to try again and enters another race on a track of different length. This time, Paul strongly suspects that his opponent cheated; though they both seemed to accelerate at a uniform rate of $10.0 \text{ m}/\text{s}^2$ throughout the entire race, Paul's opponent finished $\displaystyle\Delta t = 1.3 \text{ s}$ before Paul!

If it took Paul $10.0 \text{ s}$ to complete the course, what must his opponent's initial velocity have been to finish $1.3 \text{ s}$ before Paul?

For safety reasons, some of the fastest dragsters, called top-fuel dragsters, do not race for more than 300 to 400 meters. Consider such a dragster that, when the light turns green, accelerates uniformly from rest and completes a 357 meter race in a time of 9.56 seconds. Part A: During this period, what is the dragsters acceleration expressed as a multiple of the acceleration due to gravity, g? Part B: If the dragster could continue with this average acceleration, what would its speed be, in miles per hour, after it has traveled a total distance of 1.6km, which is approximately one mile?

In his 1865 science fiction novel From the Earth to the Moon, Jules Verne described how three astronauts are shot to the Moon by means of a huge gun. According to Verne, the aluminum capsule containing the astronauts is accelerated by ignition of nitrocellulose to a speed of 11 km/s along the gun barrel’s length of 220 m. (a) In g units, what is the average acceleration of the capsule and astronauts in the gun barrel? (b) Is that acceleration tolerable or deadly to the astronauts? A modern version of such gun-launched spacecraft (although without passengers) has been proposed. In this modern version, called the SHARP (Super High Altitude Research Project) gun, ignition of methane and air shoves a piston along the gun’s tube, compressing hydrogen gas that then launches a rocket. During this launch, the rocket moves 3.5 km and reaches a speed of 7.0 km/s. Once launched, the rocket can be fired to gain additional speed. (c) In g units, what would be the average acceleration of the rocket…
