The truck has more inertia, it is bigger/heavier so it would take a lot more force to get it to change its speed/direction
Answer:
a = 0.55 m/s/s
Explanation:
As the car accelerates in forward direction the string will make some angle with the vertical direction
So here horizontal component of the tension force will accelerates the dice in forward direction along with the car
Vertical component of the tension force will balance the weight of the dice
so we will have
here we know that
= angle made with the vertical by string
now divide the two equations
so we have
I think it is B I hope it is correct
