A 55.0-kg skydiver drew falls for a period of time before opening his parachute. what is his kinetic energy when he reaches a ve
Jlenok [28]
Mass (m)=55kg

acceleration (a)=9.81 m/s^2, this is the acceleration due to gravity.

initial velocity=0m/s. The skydiver doesn’t start with any speed because she is on the plane or helicopter.

final velocity=16m/s This is the velocity (speed) the skydiver reaches

The equation we use is KE=.5mv^2
Kinetic energy=.5 mass x velocity^2

KE=.5(55kg)(16m/s)^2
KE=.5(55kg)(256m/s)
KE=.5(14080J)

J=Joules

KE=7040J

Kinetic energy is 7040 Joules (J)

Hope this helps

Which type of stress causes deformation that leads to earthquakes at converging plate boundaries?
ki77a [65]
The answer is <em>Compressional Stress
</em>

In geology, stress<span> is the force per unit area that is placed on a rock. ... This is called confining </span>stress<span>. Compression squeezes rocks together, </span>causing<span> rocks to fold or fracture (break). Compression is the most common </span>stress<span> at </span>convergent plate boundaries<span>.
