Answer:
Explanation:
The acceleration of the car is given by:
where
v is the final velocity
u is the initial velocity
t is the time
Here we have to convert the velocities from mi/hr to m/s. Keeping in mind that
1 mi = 1609 m
1 h = 3600 s
We get:
While the time interval is
t = 4.0 s
Substituting,
Answer:
Speed = 10.24 m/s.
Explanation:
<u>Given the following data;</u>
Distance = 100m
Time = 9.77
To find her speed;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
Substituting into the equation, we have;
<em>Speed = 10.24 meter per seconds. </em>
