Answer:
693.685 N
Explanation:
t = Time taken
u = Initial velocity = 27 m/s
v = Final velocity
s = Displacement = 578 m
a = Acceleration
m = Mass
Equation of motion
Force
F = ma
Magnitude of braking force required to stop the car is 693.685 N

Option a) 0.8 m/s² is the correct answer
the acceleration of the motorcycle is 0.8 m/s²
Given the data in the question;
Since the motorcycle stopped then, initial speed u = 0 m/s
final speed v = 12 m/s
time t = 15 s
acceleration = ?
To get our acceleration, we use the first equation of motion.
This equation states that;
so, we simply substitute in our given values
so we find a
Therefore, the acceleration of the motorcycle is 0.8 m/s²
Option a) 0.8 m/s² is the correct answer
