You push the shopping cart uphill in the garage with the force Fp (i⃗ cosα + j⃗ sinα) at ​​a distance of 15 m (i⃗ cosθ + j⃗ sinθ), where the angle θ = 17 ∘ indicates the horizontal inclination of the floor. The absolute value of the thrust is Fp = 62.93 N and the direction α = -3.0 ∘ is slightly lowered and is also multiplied by the horizontal plane. As a result of pushing, the carts move at a steady speed. The weight of carts with shopping is 19 kg.

a)Determine how much work gravity Wmg will do for the cart?

b)Determine how much work the floor support will do for the cart?

c)Determine how much work you do on the cart?

    A. A crate of mass 66.8 kg rests on a level surface, with a coefficient of kinetic friction 1.49. You push on the crate with an applied force of 1,178. What is the magnitude of the crate's acceleration as it slides? Part A answer: 3.0327 m/s^2 B. Take the same crate of mass 66.8 kg and the same coefficient of kinetic friction 1.49, but now place the crate on an inclined surface, slanted at some angle above the horizontal. Now...
