a 7650 kg helicopter is raising a 1250 kg payload above a construction site with an acceleration of .80 m/s2. the payload is attached to the helicopter with a cable. a. what is the lift force needed to accelerate the helicopter upwards? b. what is the tension in the cable supporting the payload? c. what force does the cable exert on the helicopter?

A) A helicopter must accelerate upward with a 94340 N lift force.

As stated by Newton's second law, FL=(m+M)(g+a)= =(1250+7650)(9.8+0.8)=94340 N.

B) The following is the result of the forces' equilibrium: T=m(g+a)=13250 N, T=mg=ma.

C) The tension, or 13250 N, is this force.

What connection exists between speeds and accelerations?

The change in displacement is measured in terms of velocity. The rate at which something changes speed is measured by acceleration. Since velocity has both a magnitude and a direction, it is an example of a vector quantity.

Which three elements accelerate the process?

Accelerated motions can be divided into three categories: average acceleration, non-uniform acceleration, and uniform acceleration. when an object accelerates in equal-interval increments while moving straight.
