I think its 1,2 sorry if wrong
Answer:
The maximum acceleration the train can have without causing any actors to slide off = 8.232 m/s²
Explanation:
As long as the force of the moving train (on the actors), that causes acceleration doesn't exceed the frictional force between the shoes of the actors and the train, the actors will not slide off.
The maximum acceleration is the acceleration that corresponds to just when this acceleration causing force matches the frictional force.
Frictional force per actor = μN
where N is the normal reaction of the train on each actor and it is equal to mg, the weight of each actor.
The force causing acceleration = ma
So, ma = μ mg
Such that the masses can cancel out
a = μ g = 0.84 × 9.8 = 8.232 m/s²
Therefore, the maximum acceleration the train can have without causing any actors to slide off = 8.232 m/s²
I've got a great idea ! Let's calculate the car's average speed !
Average speed = (distance covered) / (time to cover the distance)
Distance covered = (position at the end) - (position at the beginning)
= (295.7 m) - (176.5 m) = 119.2 m
Average speed = (119.2 m) / (12.4 s) = 9.61 'm' per 's' .
