Answer:
Acceleration = 0.1464 m/s^2
Step-by-step explanation:
From the question, the parameters given are:
Mass m = 1000 kg
The driver and a help pulled it with two ropes respectively with forces 200√2 N 45° east of south and 400N 30° north of east
Find the resultant force along the x axis.
(400 × cos30) - (200√2 × cos45)
346.4 - 200 = 146.4 N
therefore, the resultant force = 146.4N
The formula to use for the acceleration of the car is
F = ma
Where
F = resultant force
M = mass of the car
a = acceleration of the car
Substitute f and m into the formula
146.4 = 1000 × a
Make a the subject of formula
a = 146.4 / 1000
a = 0.1464 m/s^2
Therefore, the car accelerate at 0.1464 m/s^2
