Force*time= massball*changeinvelocty
I am beginning to wonder if you are doing the algebra in your head and messing up there.
A force of 200 N acts on a 7.20-kg bowling ball for 0.350 s. Calculate its change in velocity.
7.20/0.350
= 20.57 m/s

nope this is all calculator
200*.350
= 70 m/s
= 70 m/s
I never had a calculator that could think.
I havent either
Many of the equations that you write down here and elsewhere are incorrect and could be easily verified if you kept track of dimensions.
(change in V, m/s)
= (Force, kg*m/s^2)*(time,s)/(Mass, kg)
= 200*0.350/7.2 = 9.7 m/s
(1 N is the same as 1 kg*m/s^2)
When showing your work, write down the equation you are using and check its dimensions yourself first. You will be able to find and correct many of your own mistakes
