Answer:
20 N
Step-by-step explanation:
because of newton's second law you will use this equation F=ma which means force= mass*acceleration
so your problem should look like this 5*4=20
D is a notation for differential. There is a d2 in your formula because in the numerator there are two differentials. The formula is thus the second derivative of a function with respect to two variables.
19200 all you have to do to figure this out is multiply 100 times 8 since the is 8 halfs in 4 hours.
