You need to multiply the two numbers. Or you can use long addition.
Y = - 20x + 100
Slope is -20, y-intercept is 100.
Answer: John has an object suspended in the air. It has a mass of 50 kilograms and is 50 meters above the ground. Calculate the object's potential energy.
Step-by-step explanation:
Calculate the potential energy for a 2 kg basketball dropping from a height of 3.5 meters with a velocity of 9.8 m/sec².
You don't say if the answer needs to be rounded
the height is 77.27 meters ( not rounded)
