Answer:Velocity can be represented by an arrow, with the length of the arrow representing speed and the way the arrow points representing direction. Objects have the same velocity only if they are moving at the same speed and in the same direction. ... The SI unit for velocity is m/s, plus the direction the object is traveling.

Answer:
4.245s
Explanation:
Given that, 
Hypothetical value of speed of light in a vacuum is 18 m/s
Speed of the car, 14 m/s
Time given is 6.76 s, and we're asked to find the observed time, T
The relationship between the two times can be given as 
T = t / √[1 - (v²/c²)]
The missing variable were looking for is t, and we can find it if we rearrange the formula and make t the subject 
t = T / √[1 - (v²/c²)]
And now, we substitute the values and insert into the equation 
t = 6.76 * √[1 - (14²/18²)]
t = 6.76 * √[1 - (196/324)]
t = 6.76 * √(1 - 0.605)
t = 6.76 * √0.395
t = 6.76 * 0.628
t = 4.245 s
Therefore, the time the driver measures for the trip is 4.245s
 
        
             
        
        
        
Answer:
a)-1.014x  J
J
b)3.296 x   J
J
Explanation:
For Sphere A:
mass 'Ma'= 47kg
xa= 0
For sphere B:
mass 'Mb'= 110kg
xb=3.4m
a)the gravitational potential energy is given by
  = -GMaMb/ d
 = -GMaMb/ d
 = - 6.67 x
= - 6.67 x  x 47 x 110/ 3.4 => -1.014x
 x 47 x 110/ 3.4 => -1.014x  J
J
b) at d= 0.8m (3.4-2.6) and  =-1.014x
=-1.014x  J
J
 
The sum of potential and kinetic energies must be conserved as the energy is conserved.
 +
 +  =
=  +
 + 
As sphere starts from rest and sphere A is fixed at its place, therefore  is zero
 is zero
 =
=  +
 + 
The final potential energy is
  = - GMaMb/d
= - GMaMb/d
Solving for ' '
 '
 =
 =  + GMaMb/d => -1.014x
 + GMaMb/d => -1.014x  + 6.67 x
 + 6.67 x  x 47 x 110/ 0.8
 x 47 x 110/ 0.8
 = 3.296 x
 = 3.296 x   J
J
