Fastest Ride

I would like to get from City A to City B, which are 200 miles apart, in the shortest amount of time, given the stipulation that I don't want to experience a force more than 4 times the force of gravity. What is shortest amount of time this trip can take?

Car and Motorcycle

A force is applied to a 1000 kg car, and causes the car to accelerate from 0 m/s to 25 m/s while traveling 200 m. The same force is applied to a 600kg motorcycle.  How far will the motorcycle travel while accelerating from 10 m/s to 40 m/s?

M1 and M2

A mass, m1, accelerates at 3 m/s2 when a force, F, is applied. A second mass, m2, accelerates at 1.0 m/s2 when F is applied to it.

  1. Find the value of the ratio m1/m2.
  2. Find the acceleration of the combined mass ( m1 + m2) under the action of the force, F.
     

Luke Skywalker's X-Wing

After Luke Skywalker got his X-Wing fighter out of the swamp on Dagobah, he wanted to make it fly. The mass of the ship is 5,000 kg. Luke applies (using the force) an upward force of x Newtons. Yoda, who doesn't want Luke to get too confident, applies a downward force which is two-thirds of Luke's force.

Luke's Skywalker X-Wing fighter lifts off to a height of 2 km in 5 seconds. How much force did Luke apply?
