Explanation:
Write equations for the position of each car as a function of time. (Make sure to convert units if they're different.)
The red car's position x at time t is:
x = (14.41 cm/s) t + 60 cm
The blue car's position x at time t is:
x = (41.32 cm/s) t
To find when they meet, set the equations equal to each other.
(14.41 cm/s) t + 60 cm = (41.32 cm/s) t
60 cm = (26.91 cm/s) t
t = 2.230 s
Answer: True
Explanation:
Class characteristics can be define as the features which are common to the group of objects. Like the make, model, label of the manufacturing company, design, shape and form. The individual characteristics can be define as the features which develop on the object or any other article with it's wear and use. Like tear, cuts, malformation and deposition of dust, dirt, and mud. The individual characteristic indicate towards the ownership of article or evidence to a particular person.
The class characteristics can only support the possibility of the evidence exactly alike that of the evidence found at the scene of crime. But the individual characteristics can directly link the evidence with the cause of crime. Hence, will be useful to prove that a crime has taken place in the court of law.
during free fall acceleration doesn't depends on initial speed
in free fall acceleration is given by
so for all cases of initial speed its acceleration is always equal to "g" and magnitude equal to 9.81 m/s^2
