Answer:
Situation 2, 4, 5
Since there are five situations I just numbered them 1-5
Explanation:
Using kinematics,
t = 4s
u = 0m/s
a = 9.8m/s^2
Therefore v = u + at = 0 + (4)(9.8) = 39.2m/s.
Answer:
im not 100 percent but its probably 2 turtles 20m apart
Formula: Fc=mv^2/r
Fc = centripetal force = to be determined
m = mass of the car = 1,150 kg
r = radius of the circle in which the car is traveling = 44 m
v = linear velocity of the car = 13 m/s
Fc= 1150*(13^2)/44
Fc= 4417.045
Hope this helps!
Good luck! :)
