Let the first car's average speed be x
The second car's speed would be x+5




So the speed of the slower car is 50mph, and the speed of the faster car is 55mph
 
        
        
        
a. 46 m/s east
The jet here is moving with a uniform accelerated motion, so we can use the following suvat equation to find its velocity:

where
v is the velocity calculated at time t
u is the initial velocity
a is the acceleration
The jet in the problem has, taking east as positive direction:
u = +16 m/s  is the initial velocity
 is the acceleration
  is the acceleration
Substituting t = 10 s, we find the final velocity of the jet:
 
And since the result is positive, the direction is east.
b. 310 m
The displacement of the jet can be found using another suvat equation
 
where
s is the displacement
u is the initial velocity
a is the acceleration
t is the time
For the jet in this problem,
u = +16 m/s  is the initial velocity
 is the acceleration
  is the acceleration
t = 10 s is the time
Substituting into the equation,

 
        
             
        
        
        
TP hydrolysis distinct from any incorporation into the chain.

Answer:
Negative acceleration occurs when the acceleration vector points to the left.
1. Object slowing down in the positive direction.
2. Object speeding up in the  negative direction.
