Answer:
The magnitude of the acceleration of the box is 1.664 m/s².
Step-by-step explanation:
Given that,
Mass of box = 3.00 kg
Angle = 34.5°
Distance = 2.00 m
Time = 1.55 s
We need to calculate the magnitude of the acceleration of the box
Using equation of motion
![s = ut+(1)/(2)at^2](https://img.qammunity.org/2020/formulas/physics/college/dog554vw1dit8wg2q6uvdx1txzf2v6g2wx.png)
![a=(2s)/(t^2)](https://img.qammunity.org/2020/formulas/physics/college/ujmuifzx4xpt1spwcjjrju068xgnk0jvqz.png)
Where, s = distance
t = time
a = acceleration
Put the value into the formula
![a=(2*2.00)/(1.55^2)](https://img.qammunity.org/2020/formulas/physics/college/9dof9fe57lr1m17md59q9sunw5h3w2os49.png)
![a=1.664\ m/s^2](https://img.qammunity.org/2020/formulas/physics/college/1gpuiy5dk4bzmxs0up3qc81zu2ac2bw2ug.png)
Hence, The magnitude of the acceleration of the box is 1.664 m/s².
