Here it is given that initial speed of the package will be same as speed of the helicopter
displacement of the package as it is dropped on ground
acceleration is due to gravity
now by kinematics
by solving above equation we have
so it will take 5.2 s to reach the ground
Your question is not complete
For this I can answer only this
That it can stop in 3 seconds
A technique in which the muscles are stretched by an outside force is called Passive Stretching
Answer:
Uniform acceleration because the speed is increasing
AC can be produced using a device called an alternator. This device is a special type of electrical generator designed to produce alternating current. A loop of wire is spun inside of a magnetic field, which induces a current along the wire.
