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?

The displacement vector from the grocery store door to your car is ∆x = (5 i – 8 j ) m But because of the strong gust, you have to apply a force F in a slightly different direction to keep your cart moving straight from the door to the car. F = (30 i + 5π j ) N How much work do you do?

A Review | Constants Part A A 57.0 kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it, and the crate just begins to move when your force exceeds 313 N. Then you must reduce your push to 208 N, to keep it moving at a steady 25.0 cm/s. What are the coefficient of static and kinetic friction between the crate and the floor? Enter your answers numerically separated by a comma....

Can someone please help me with D and E.
Constants Part A To understand the magnetic force on a straight current-carrying wire in a uniform magnetic field. Magnetic fields exert forces on moving charged particles, whether those charges are moving independently or are confined to a current- carrying wire. The magnetic force Fon an individual moving charged particle depends on its velocity and charge er. In the case of a current-carrying wire, many charged particles are simultaneously in motion, so...

5) (10 pts) John is baby-sitting Casey, his 3-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As John starts across the street, he exerts a 58 N forward force on the wagon. There is a 20 N resistance force (friction) and the wagon and Casey have a combined weight of 302 N. Construct a free body diagram showing all the forces acting upon...
