In many cartoons, the lift ramps in roller coasters reach into space. Suppose a 200kg roller coaster car starts at an altitude of 70 km.

1.In many cartoons, the lift ramps in roller coasters reach into space. Suppose a 200kg roller coaster car starts at an altitude of 70 km. The roller coaster track consists of a single drop, and a horizontal section at sea level (0 km altitude). Assuming no friction or air resistance, and g = 9.81 m/s2 throughout the entire track, what is the car’s speed on the horizontal section?For reference, the top speed of the SR-71 spyplane is 980 m/s.
