In this particular question, for first part, let's call it part one.
00:05
So for part one, we have mass that is equal to 65 .7 kilogram.
00:13
D we have that is supposed to 18 meters.
00:16
D we have that is equals to 0 .849 second.
00:21
All right a with the acceleration of human cannon ball.
00:31
Using s equals u2 plus half 80 square, we can write d will be equal to half.
00:39
Square from here a is equal to 2d over t squared putting the values this is is equal to price of 18 over 0 .849 square 75 this will give us 49 .94 meters per second per second now we have acceleration and we know mass so f will be equal to 69 .7 times 49 .9.
01:15
9 volt this is equals to 3281 .35 newton this will be the answer for the first part that is part a.
01:28
Now for second part we have m that is equal to 1180 kilogram u that is equal to 37 .2 meters per second then we have p that is equals to 7 .8 2 seconds v that is equal to 9.
01:55
Meters per second now acceleration is equal to v minus u over d putting the values you you will have 19 minus 37 .2 over d that is equals to 7 .82 this is equal to minus 2 .327 meters per second per second okay we know acceleration and we know mass so now force will be equal to just putting the values 118 times 2 .327 this equals to 2746 .29 newton.

This really the answer for the second part...
