A 17-year-old employee working for Southern Virginia College's (SVC) bookstore during the summer months is helping prepare for Fall sales. It's a good way to make extra money, and the teen is saving for a car.
Books from one supplier are shipped to the SVC bookstore in large crates equipped with rope handles on all sides. On one occasion, the teen momentarily pulled with a force of 707 N at an angle of 33.7° above the horizontal to accelerate a 121-kg crate of books. The coefficient of friction between the crates and the vinyl floor is 0.55.
Determine the acceleration experienced by the crate in m/s2. Use the approximation g ≈ 10 m/s2.
A 1.00 × 103-N crate is being pushed across a level floor at a constant speed by a force → F of 3.00× 102 N at an angle of 20.0° below the horizontal, as shown in Figure a. (a) What is the coefficient of kinetic friction between the crate and the floor? (b) If the 3.00 × 102-N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in Figure b, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in part (a).

- A mule is harnessed to a sled having a mass of 201 kg, including supplies. The mule must exert a force exceeding 1270 N at an angle of 30.3° (above the horizontal) in order to get the sled moving.

N (b) Find the coefficient of static friction between the sled and the ground beneath it.

Narrow_forwardYou are a member of an alpine rescue team and must get a box of supplies, with mass 2.80 kg , up an incline of constant slope angle 30.0 degrees so that it reaches a stranded skier who is a vertical distance 3.10 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00×10^−2. Since you can't walk up the incline, you give the box a push that gives it an initial velocity; then the box slides up the incline, slowing down under the forces of friction and gravity. Take acceleration due to gravity to be 9.81 m/s2. Use the work-energy theorem to calculate the minimum speed v that you must give the box at the bottom of the incline so that it will reach the skier.arrow_forwardA luggage handler pulls a 20.0 kg suitcase up a ramp inclined at 33.0° above the horizontal by a force F of magnitude 167 N that acts parallel to the ramp.
