Answer:
200.96
Step-by-step explanation:
The formula for area of a circle is A=pi*r(2)
A = 3.14 (64)
A = 200.96
A) It needs to be mixed fractions so, 4/3 x 9/2
B) 2/3 x 3/4
Answer:
Assuming both people are pulling in the same direction, the net force on the car is, according to Newton's second law,
600 N + 800 N - 1200 N = (2250 kg) a
Solve for the acceleration a :
200 N = (2250 kg) a
a = (200 N) / (2250 kg)
a ≈ 0.0889 m/s/s
Step-by-step explanation: I hope this helps!
Answer:
