Answer:
5m/s²
Explanation:
Given parameters:
Initial velocity = 10m/s due east
Final velocity = 30m/s due east
Time = 4s
Unknown:
Acceleration of the car = ?
Solution:
Acceleration is the rate of change of velocity with time.
Mathematically;
Acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Insert the parameters and solve;
Acceleration = = 5m/s²
Answer:
Explanation:
The main thing for this equation is to follow the amount on each side. Count each element on each side. Then by looking at the numbers figure out what numerical digit would make them equal.
For example:
On the left we have
Cu=1 and Cl=2.
But on the right we have
Cu=1 and Cl=3.
In order for them to be the same, we must add a coefficient of 3 to CuCl2 (aq0 on the left and a coefficient of 3 to Cu(s) on the right.
