You work for the police. An accident has happened. A farmer was taking his dairy cows for milking across a road. The crossing point was 100m from a blind bend. In normal conditions with an alert driver obeying the speed limit of 30m/s a car can safely stop before reaching the crossing point. Mr Hoyland was driving home, saw the cows around the bend and was unable to stop. He ran into one of the cows and killed it.

A farmers accident.

As your work is for police an accident has happened. The farmer was taking his cows for milking across the road. The responsibility of both the farmers and driver in accident is taken into consideration.

The answers is before the crash.

As far as the accident could take place when is walking blind from behind. The pointing crossing was 100m from the farm.As stopping distance is less than the thinking distance, it is this possible to run into an accident. As the car could have stopped before the crash.

Answer from: gisset9

Since the stopping distance is less than the thinking distance, Mr Hoyland is therefore responsible for the accident

Explanation:

. In normal road conditions and with an alert and sober driver the car

could have stopped before the crash.

2. The reaction time of an alert and sober driver is 0.6s.

3. The reaction time of a drunk driver could be 2s.

4. The initial speed of the car was 30m/s

5. From the time of applying the brakes the total braking distance in

normal conditions is 70m

6. From the time of applying the brakes the total braking distance in bad

conditions is 90m

7. From the time of applying the brakes in normal conditions the car would

reach 15m/s in 52m

You are a forensic expert working for the police. You must analyse the facts and produce a

report stating whether or not Mr Hoyland was responsible for the accident.

1. Calculate the thinking distance for a car travelling at 30m/s

2. Calculate the braking distance for a car travelling in normal conditions at 30m/s

3. Calculate the total stopping distance.

4. REMEMBER TO SHOW YOUR WORKING OUT

Challenge:

1. Is Mr Hoyland responsible for the accident?

2. Explain your answer giving CLEAR reasons for your answer and likely causes.

The Thinking distance = 100m

The breaking distance = 70m

A breaking distance = Stopping distance = 70m

Since the stopping distance is less than the thinking distance, Mr Hoyland is therefore responsible for the accident

Texture and composition are different because they are not the same aspect. texture has to do with feel and so on, where as composition is the chemical makeup which you cant touch like you can texture.

Answer from: Quest

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
