A ball is thrown upward at time t=0 from the ground with an initial velocity of 18 m/s (~ 40 mph). Assume that g = 10 m/s2. Time to reach apex 18/10 = 1.8 Time x 2 = 3.6 Great height reached by ball – (Velocity)(time)+(-5)(time^2) 18x1.8+(-5)(1.8^2)=16.2 A model rocket accelerates upward from the ground with a constant acceleration‚ reaching a height of 63 m in 8 s. * Speed at height 63 - 2x63/8 = answer What is the acceleration= answer/8 * If you were to drop a rock from a tall building

Matt Ennis 10/3/10 The Use of Force A physician is summoned to make a housecall on a family with who he has had no prior contact. He quickly sizes up the situation: the household is poor but clean; the patient is a female child whose parents are nervously concerned‚ dependent on‚ yet skeptical of the doctor. The child ’s beauty and piercing stare make an immediate impression on him. Concerned that diphtheria may be the cause of illness‚ he uses his customary professional manner

The electric field depicts the surrounding force of an electrically charged particle exerted on other electrically charged objects. The concept of an electric field was introduced by Michael Faraday. The electric field is a vector field with SI units of newtons per coulomb (N C−1) or‚ equivalently‚ volts per metre (V m−1). The SI base units of the electric field are kg⋅m⋅s−3⋅A−1. The strength or magnitude of the field at a given point is defined as the force that would be exerted on a positive test

Drinking and Driving Drunk driving is considered a serious crime in every state. It is wrong‚ irresponsible and wastes many lives. People who abuse alcohol hurt everyone around them‚ endanger public safety‚ and create chaos on the nation’s highways. There is nothing positive that can come out of drunk driving‚ so why do people do it? It is society’s job to punish these people and try to take control of this “out of control” issue. America doesn’t want to watch quietly as hundreds of people are killed

FORCE AND MOTION Scalars vs. Vectors Scalars | Vectors | A scalar quantity has only magnitude. | A vector quantity has both magnitude and direction. | Scalars can be added‚ subtracted‚ multiplied and divided just as ordinary numbers‚ i.e.‚ scalars are subjected to simple arithmetic operations. | Vectors cannot be added‚ subtracted and multiplied following simple arithmetic laws. Arithmetic division of vectors is not possible at all. | Example: mass‚ volume‚ time‚ distance‚ speed‚ work‚ temperature

Driving Restrictions There are many accidents everyday that are costing people their lives. My young brothers and most definitely my grandparents would probably kill me for saying so‚ but there should be some changes made to the laws concerning the age requirements of drivers. If the State of Ohio changed the age requirement of operating a vehicle to between 18-70 years of age‚ our roads would be much safer to drive on.

Dear Mom and Dad‚ I’ve really been thinking about this whole driving incident‚ These past few days have made me see it differently. I’ve learned that this isn’t necessarily about keeping insurance rates down or keeping a good reputation‚ Head injuries are extremely common in car accidents and after seeing what happened to Zack‚ I could never let you guys go through that.

Definition of Force A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects‚ there is a force upon each of the objects. When the interaction ceases‚ the two objects no longer experience the force. Forces onlyexist as a result of an interaction. Velocity‚ Acceleration‚ Momentum‚ and Impulse Velocity‚ in physics‚ is a vector quantity (it has both magnitude and direction)‚ and is the time rate of
