Question

q1 -

A student is pulling a crate with a mass of 20.0 kg along a horizontal frictionless floor with a rope that’s inclined at an angle θ = 30.0° above the horizontal as shown. The tension force is measured to be 150 N. What is the magnitude of the acceleration, in m/s²? Use g = 10.0 m/s².

q2 -

During your winter break, you enter a sled race. You push the sled with a force of 210 N at 30.0° below the horizontal as shown. The mass of the sled (and your nephew sitting on it) is 35.0 kg. The coefficients of friction between the sled and icy surface are μ_s = 0.35 and μ_k = 0.20. What is the magnitude of the acceleration of the sled, in m/s²? Use g = 10.0 m/s².

Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer; it is already given in the question statement.

**Diagram Explanation:**

The diagram shows a person pulling a crate with a rope. The rope is inclined at an angle of 30° above the horizontal direction. A tension force is indicated along the rope. Several objects are placed inside the crate.

**Problem Statement:**

During your winter break, you enter a sled race. You push the sled with a force of 210 N at 30.0° below the horizontal as shown. The mass of the sled (and your nephew sitting on it) is 35.0 kg. The coefficients of friction between the sled and icy surface are \( \mu_s = 0.35 \) and \( \mu_k = 0.20 \). What is the magnitude of the acceleration of the sled, in m/s²? Use \( g = 10.0 \, \text{m/s}^2 \).

*Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer; it is already given in the question statement.*

**Selected Answer:** 3.8

**Diagram Explanation:**

The diagram shows a person pushing a sled with a force vector labeled as 210 N at an angle of 30° below the horizontal. The vector is directed towards the sled, implying an applied force at an angle contributing to the motion along the icy surface.
