Question

#1) After a heavy snow, emma has trained her squirrel, named Jeff, to ride in a sled. hops in the sled on a snow bank that has an angle of 35° relative to the horizontal. The total mass of Jeff and the sled together is 0.85kg, and there is no frictional force between the sled and the snow surface. The magnitude of the gravitational acceleration is 9.8 m/s². (You need to draw a sketch and FBDs). (A) Find the acceleration of Jeff and the sled combination. (B) Find the normal force exerted on Jeff and the sled combination. #2) emma's squirrel, named Jeff pulls a 0.11 kg suitcase horizontally with an acceleration of 0.15 m/s² an angle of 45° of force above the horizontal. There is no frictional force between the suitcase and the surface of ground. The magnitude of the gravitational acceleration is 9.8 m/s². (You need to draw a sketch and FBDs) (A) How much force is applied by Jeffon the suitcase? (B) How much normal force is exerted on the suitcase? #3) ???? hangs a squirrel picture on the wall suspended by two strings. String 1 exerted a force $T_1$ with a magnitude of 2.4 N at angle of 73° above the horizontal. String 2 exerts a force $T_2$ at angle of 47° above the horizontal as shown the figure. The magnitude of the gravitational acceleration is 9.8 m/s². (You need to draw FBD) (A) What is the magnitude of a force $T_2$ in string 2? (B) What is the mass of the picture?
