Answer:
magnitude : 0.6 m/s²
Direction : Left
Explanation:
m = mass of the cart = 90 kg
Taking force in right direction as positive and force in left direction as negative
F₁ = Force applied by man 1 = 140 N
F₂ = Force applied by other man = - 195 N
a = acceleration of the cart
Force equation for the motion of the cart is given as
F₁ + F₂ = ma
140 + (- 195) = 90 a
a = - 0.6 m/s²
magnitude of acceleration is 0.6 m/s²
The negative sign indicates the direction of acceleration towards left
