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 = [tex]\frac{v - u}{t}[/tex]
v is the final velocity
u is the initial velocity
t is the time taken
Insert the parameters and solve;
Acceleration = [tex]\frac{30 - 10}{4}[/tex] = 5m/s²
