Answer:
30.56%
Step-by-step explanation:
Let the sides on each dice be labeled as 1, 2a, 2b, 2c, 3, 4.
The sample space for the sum of the values being 4 is:
S={1,3; 3,1; 2a,2a; 2a,2b; 2a,2c; 2b,2a; 2b,2b; 2b,2c; 2c,2a; 2c,2b; 2c,2c}
There are 11 possible sums out of the 36 possible outcomes that result in a sum of 4. Therefore, the probability their total is 4 is:
There is a 30.56% probability that their sum is 4.
Applying Newton's Second Law, it is found that the force, in Newtons, is given by:
Newton's Second Law states that Force, in Newtons, is <u>mass times acceleration</u>, that is:
In this problem, mass of 50 kg, thus
Acceleration is <u>change in velocity divided by change in time</u>, that is:
In this problem, we don't know the velocities, but know that time is from 16s to 21s, thus:
Thus, the force is given by:
