A loaded grocery cart of mass 50 kg starts rolling across a parking lot due to strong wind, with a constant acceleration of a = -0.18 -0.08 ſms? (1) What is the displacement vector of the cart after a time of 12.25 s? (ii) Thus, what was the distance traveled by the cart? (iii) How much work does the wind do on the cart? (iv) What is the angle between the displacement vector and the force vector?

To drag a 25.0-kg crate across a rough concrete parking lot, you decide to Pull horizontally with 100 N of force on a rope attached to the crate. The coefficient of kinetic friction between the crate and the concrete is mu_k = 0.30. Draw a free body diagram of the crate, along with a coordinate system. What is the magnitude and direction of the force of friction Find the acceleration of the crate. Once you get the crate sliding, how...
