Assuming acceleration is 10
let the final velocity be x
(x-0) /1.75= 10 where 0 is initial velocity at its highest point
x= 17.5m/s

Answer:

v_f=17.15\frac{m}{s}

Explanation:

The apple is in free fall, therefore we can use the kinematic equations, especifically the which one that relate final speed to acceleration of gravity and time:

g=\frac{v_f-v_o}{t}

The initial speed is zero, since falls out of the tree and recall that g=9.8\frac{m}{s^2}. So, Rewriting for final speed:

v_f=gt\\v_f=(9.8\frac{m}{s^2})(1.75s)\\v_f=17.15\frac{m}{s}

How can we calculate force
lutik1710 [3]

To calculate force, use the formula force equals mass times acceleration, or F = m × a. Make sure that the mass measurement you're using is in kilograms and the acceleration is in meters over seconds squared. When you've solved the equation, the force will be measured in Newtons.

12. your friend with great excitement tells you about his newest idea to solve the energy crisis: he wants to use an electromoto
mixas84 [53]
I would tell him, in the kindest, most gentle way I could manage,
to fahgeddaboudit. 

The total amount of energy doesn't change.  Energy is never created,
and it never disappears.  If you have some energy, then it had to come
from somewhere, and if you used some energy, then it had to go
somewhere. 

You can never get more energy out of the electromotor than you put into it,
 and in the real world, you can't even get THAT much out, because some
of it is always used on the way through.

Pour yourself a cold glass of soda, then look up "Perpetual Motion" or
"Free Energy" on the internet, relax, and enjoy the show.  They are all
fakes.  They may not all be intentionally meant to fool you, but they are
all impossible.
