A sky-diver jumps from a stationary balloon. His initial downwards acceleration is 10m/s².

Fig. 1.1 shows the directions of the air resistance and the weight of the sky-diver.

The mass of the sky-diver is 60 kg and his weight is 600 N.

Explanation:

a. The force acting down is gravity, on Earth gravity is 10 m/s^2. When the skydiver jump, the acceleration will start out as -10 m/s^2, but it will eventually equals the air resistance , which is called terminal velocity.
