4. A jet plane traveling at 88 m's lands on a runway and is decelerated (negative acceleration) to rest in 11.0 seconds.

(a) Calculate the plane's acceleration?

(b) Calculate the distance the plane travels during the 11.0 s.

Discard my wrong work lol

Ahydroelectric plant takes energy from water and turns it into electrical energy. what are the transformations of energy in the water molecules that are used in the process of generating electricity this way?

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
