The tension in the string that accelerates a 5 kg cart to 2 m/s² is equal to 10 Newton.
Explanation:
Tension:
Tension is a force exerted by the rope, Tension refers to the pulling force transmitted axially by the means of a string, cable or a chain.
In the given case, Tension in the string is simply the pulling force it applies on the cart. There is no special formula for tension in the string.
Newton's second law is often stated as F = ma, which means the force (F) acting on an object is equal to the mass (m) of an object times the acceleration (a) produced in it due to that force.
Mass of the cart = 5 kg
Acceleration produced = 2 m/s²
Tension in the string = F = ma
= 5*2
= 10 kg m/s²
= 10 N
