A zoologist pulls a block of hay towards an animal enclosure. The zoologist pulls at the angle of 27 degrees above the horizontal with a constant speed of 1 m/s. The mass of the hay is 60 kg and the coefficient of friction between the hay and the concrete is 0.29What is the value of the force F the zoologist is applying? F 0

A sled of mass 87 kg is being pushed up a slope with an applied force of 853 N. The slope is inclined with an angle of 34 degrees with respect to the horizontal. The coefficient of friction between the sled and the hill is 0.29. The acceleration of the crate (in m/s²) is:

In the figure here, a box of Cheerios (mass mc = 1.70 kg) and a box of Wheaties (mass mw = 2.60 kg) are accelerated across a horizontal surface by a horizontal force applied to the Cheerios box. The magnitude of the frictional force on the Cheerios box is 2.10 N, and the magnitude of the frictional force on the Wheaties box is 4.60 N. If the magnitude of F is 12.7 N, what is the magnitude of the force on the Wheaties box from the Cheerios box? Number i Unit

Just like Louis, Maria left a book on the roof of her car before driving away. The mass of the book was 725 grams. The coefficient of static friction between the book and the roof was 0.28. The coefficient of kinetic friction between the book and the roof was 0.23. Maria started her car and drove forward on level ground with an acceleration of 3.6 m/s?. As Maria was driving away with that acceleration, what was the magnitude of the force of friction (in newtons) between the book and the roof of the car?

Bran is pushing Amira in a sled. The combined mass of the sled and Amira is 40.0 kg. There is a coefficient of kinetic friction between the led and the snow of 0.205. Bran applies a 160 N pushing force at 30.0° below the horizontal. What is Amira's acceleration? (Give your answer in m/s2.)

An applied force of 95.6 N is used to accelerate an object across a frictional surface. The object has aweight of 45.2 N and encounters a frictional force of 60.0 N.(a) Draw a sketch of the object and show all of the forces acting on the object.(b) What is the net force acting on the object in the horizontal direction?(c) What is the net force acting on the object in the vertical direction?(d) Using Newton’s 2nd Law, find the object’s acceleration.
