To solve for the question, let's convert the given quantities into a cycle.
00:06
The speed given, that is equal to, 311 kilometers per hour.
00:14
In si, it is equivalent to 5 .80 meters per second upon kilometers per hour.
00:26
Or the given speed waves, it is 6 .4 meters per second.
00:33
And that is in the penetration the space at x is 81 cm that is equivalent to 1 meter upon 100 centimeter or that is equal to 0 .8 meter so now for part a from the second equation of the kinematic motion we can write b square is equivalent to 2 a into x or the xx acceleration a is equivalent b squared upon 2x now substitute the value zero the acceleration a comes out to the initial speed v is 86 .4 meters per second whole square upon 2 into 0 .8 meter or the acceleration is 4 ,610 meters per second square now the acceleration in terms of g is, the acceleration is 4 ,610 upon 9 .80 meters 4 second square and allow also meters 4 second square into g.
02:04
Or in terms of g, the acceleration is 417 cheats.
02:14
For part b, for part b, the force exerted, f is equal to m into 8 or the force is the mass of the genesis is 210 kg and the acceleration is 4 ,610 meters 4 seconds squared or the force exerted is 9 .68 into 10 rise 5 newton...
