On her way to visit Grandmother, Red Riding Hood sat down to rest and placed her 1.20-kg basket of goodies beside her. A wolf came along, spotted the basket, and began to pull on the handle with a force of 6.40 N at an angle of 25° with respect to vertical. Red was not going to let go easily, so she pulled on the handle with a force of 13.5 N. If the net force on the basket is straight up, at what angle was Red Riding Hood pulling from the vertical? The whole question did not paste in on my last attempt.

Red was not going to let go easily, so she pulled on the handle with a force of 13.5 N. If the net force on the basket is straight up, at what angle was Red Riding Hood pulling from the vertical? I was given the WRONG answer this morning! The force that Red applied was 13.5N NOT 12.2 N! Use 13.5 N! I use this service primarily to check my work. If the "experts" are using the wrong values, I question if they will use the right mathematical procedures if I really have a challenge!

Two people are pushing a truck across a parking lot. The truck has a mass of about 2 × 10 kg. First, they take turns pushing. When Person A pushes the truck, the truck accelerates at a rate of 1 m/s?. When Person B pushes the truck, it accelerates at a rate of 2 m/s?(a) Both people stand behind the truck and push in the same direction. What is the net force on the truck? At what rate will the truck accelerate?(b) Person A stands at the back of the truck and Person B stands at the front, and they push in opposite directions. What is the net force on the truck? At what rate will the truck accelerate? In what direction?For both (a) and (b), draw a picture indicating the forces applied by A and B as well as the motion of the truck.
