- A drill rod is used with a air hammer for making holes in hard rock so explosives can be placed in them. How many impulsive forces act on the drill rod during the drilling? Assume the weight of the drill rod is nonimpulsive 2 1,A car traveling at 53 km/h hits a bridge abutment.A passenger in the car moves forward a distance of 65 cm (with respect to the road) while being brought to rest by an inflated air bag.What magnitude of force (assumed constant) acts on the passenger’s upper torso, which has a mass of 41 kg?One end of a 30-m rope is tied to a tree; the other end is tied to a car stuck in the mud. The motorist pulls sideways on the midpoint of the rope, displacing it a distance of 2 m. If he exerts a force of 80 N under these conditions, determine the force exerted on the car.
- 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.A car traveling at 56 km/h hits a bridge abutment. A passenger in the car moves forward a distance of 56 cm (with respect to the road) while being brought to rest by an inflated air bag. What magnitude of force (assumed constant) acts on the passenger's upper torso, which has a mass of 40 kg?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? 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!

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 degree with respect to vertical. Red was not going to let go easily, so she pulled on the handle with a force of 12.2 N.
