parachute jump

The diagram below shows a skydiver during three stages of the parachute jump. Stage 1 and 2 shows the skydiver during free fall long after the skydiver has left the plane. Stage 3 shows the skydiver after the parachute has been open for some time.

 

               
   
 
 

Stage 1
 

Stage 2
 

Stage 3

 

 

 

 

 

 

 

In Stage 1 the skydiver is travelling at a constant speed.

 

(a)State the name for this steady speed.

(b)State the names of the forces on the skydiver in stage 1.

 

................................................................................................................................................................

 

............................................................................................................................................................ [2]

 

In Stage 2 the skydiver increases his speed by tilting downwards.

 

(c)Explain how tilting downwards has altered the forces acting on the skydiver.

(d)The table below shows readings from the parachutist’s altimeter (an instrument for measuring the height above the ground) during the descent. The altimeter was later found to be inaccurate at times. At 15 seconds into the jump the parachutist tilts downwards.
