Answer:
When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached.
Answer:
the rate of change of velocity
Answer:

The ratio m_2/m_1 of the masses is 9.745
Explanation:
Formula for frequency when mass m_1 is hung on the spring:

where:
k is the spring constant
Formula for frequency when mass m_2 is hung on the spring along with m_1:

where:
k is the spring constant.
In order to find ratio m_2/m_1, Divide the above equations:

On Solving the above equation:

The ratio m_2/m_1 of the masses is 9.745
Explanation:
You walk 53m to the north, then you turn 60° to your right and walk another 45m. Determine the direction of your displacement vector. Express your answer as an angle relative to east.
Answer:
Final velocity= 84 m/s
Explanation:
V final= V initial + a * t
Vf = 0+ 12 (7)
Vf= 84 m/s
