Question

can someone show me how to calculate this

Answer 1

Answer:

0.98N,0.39N,0.08N

Explanation:

see as given GPE = weight * height

and also weight = mass * acceleration due to gravity

now in the first one

GPE of ball = weight of ball * height

0.98 = weight of ball *1

now weight of ball = 0.98

0.98N is answer you can do this  like i showed

quick tip all the weight answer is same the GPE as height is equal to just change the unit from Joules to Newton
