A cart of mass 0.8 kg on a horizontal frictionless track has a tension of 4 N applied to on side of the cart. Calculate the acceleration of the cart. (Multiple choice question)
a) 8 m/s²
b) 4m/s²
c) 5 m/s²
d) 10 m/s²

Respuesta :

Answer:

Option (c).

Explanation:

Given that,

Mass of a cart, m = 0.8 kg

Tension in the car, F = 4 N

Net force, F = ma

a is acceleration of the cart.

So,

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{4\ N}{0.8\ kg}\\\\a=5\ m/s^2[/tex]

So, the acceleration of the cart is [tex]5\ m/s^2[/tex].
