Answer:
3) 52.5 m
Explanation:
d = v₁t + 1/2at²
d = 16 m/s (5s) + 1/2(-2.2m/s²) (5s)² = 52.5 m
The car travels for 52.5m during the 5 seconds interval
In order to get the distance traveled by car, we will use the equation of motion. The equation of motion for calculating the distance is expressed as:
[tex]S = ut+\frac{1}{2}at^2[/tex] where;
- u is the initial velocity
- t is the time taken
- a is the acceleration
Given the following parameters
u = 16m/s
a = -2.20m/s²
t = 5secs
Substitute the given values into the expression as shown:
[tex]S = 16(5)+\frac{1}{2}(-2.20)(5)^2\\S=80-1.10(25)\\S=80-27.5\\S= 52.5m[/tex]
Hence the car travels for 52.5m during the 5 seconds interval.
