Block A (Mass = 2.319 kg) and Block B (Mass = 1.870 kg) are attached by a massless string as shown in the diagram. Block A sits on a horizontal tabletop. There is friction between the surface and Block A. The string passes over (you guessed it) a frictionless, massless pulley. Block B hangs down vertically as shown. When the two blocks are released, Block B accelerates downward at a rate of 2.250 m/s2.

a.) What is the tension in the string?
b.)What is the magnitude of the force of friction acting on Block A?
c.) What is the coefficient of friction between the tabletop and Block A?

a.) The tension in the string can be calculated using the equation T = mB * (g - a), where mB is the mass of Block B, g is the acceleration due to gravity, and a is the acceleration of Block B. Substituting the given values, we get T = 1.870 kg * (9.8 m/s^2 - 2.250 m/s^2).

b.) To determine the magnitude of the force of friction acting on Block A, we can use the equation Ff = μ * mA * g, where μ is the coefficient of friction between the tabletop and Block A, mA is the mass of Block A, and g is the acceleration due to gravity. However, we need to know the value of the coefficient of friction (μ) to solve this part.

c.) To find the coefficient of friction, we can rearrange the equation from part b as μ = Ff / (mA * g). However, without knowing the force of friction (Ff), we cannot determine the coefficient of friction.

To find the answers to these questions, we need to use Newton's second law and the concept of forces.

Let's start with the tension in the string between Block A and Block B.

a.) To find the tension in the string (T):
- We know the mass of Block B, which is 1.870 kg, and its downward acceleration, which is 2.250 m/s^2.
- The tension in the string can be calculated by using the equation: T = mB * g - mB * a, where mB is the mass of Block B, g is the acceleration due to gravity (9.8 m/s^2), and a is the downward acceleration of Block B.
- Plugging in the values, we get: T = (1.870 kg) * (9.8 m/s^2) - (1.870 kg) * (2.250 m/s^2)
- Calculate the value to find the tension in the string.

b.) Now, let's move on to finding the magnitude of the force of friction acting on Block A:
- To find the force of friction (Ffriction), we need to use the equation Ffriction = μ * N, where μ is the coefficient of friction and N is the normal force.
- The normal force can be calculated as the weight of Block A, which is m
