Hello everyone, we are going to understand this question here given in the question given mass of object, mass of object that is represented by m which is 10 kilogram and it starts from rest so initial speed of object initial speed of object that is represented by you which is zero and it slides down on a frictionless inclined plane with constant acceleration of 2 meter per second square.
00:50
So, value of acceleration, that is a is equal to 2 meter per second square and time t is equal to 4 second.
01:14
Now, what is the magnitude of velocity of object meter per second at the end of 4 second? so in the part 15, in the part 14, because this question is depending, this is the data given for 14 15 16 and 17 so so magnitude of velocity let the required velocity be v the required velocity the required velocity be v so v is equal to u plus a into t now substituting the value in this initial velocity is zero acceleration that is 2 meter per second square into time is 4.
02:17
So velocity of the object after 4 second is 8 meter per second.
02:27
Now solving 15.
02:29
During the 4 second, what is the distance in meter traveled by the object? let the required distance be d.
02:39
The required distance be d.
02:46
So d is equal to ut plus half, 80 square.
02:51
Here initial speed is 0 plus 1 by 2 into value of a is 2 into value of t that is 4.
02:59
Now doing further calculations we will get 16 meters.
03:03
Now solving 16 part.
03:10
So what is the net force acting on the object during the 4 seconds? let the required net force be the required net force be f.
03:29
So f is equal to m into a...
