Average speed =
(total distance covered)
divided by
(total time spent covering the distance)
Is this a trure/false? if it is then it is true
Answer:
C. 100 mph west
Explanation:
Average velocity is total displacement over total time. During the first hour, the average velocity is:
v_avg = 100 mi / 1 hr
v_avg = 100 mph west
Since the velocity is constant, the instantaneous velocity at any time equals the average velocity.
v = v_avg
v = 100 mph west
Answer:
V = 19m/s
Explanation:
Given the following data;
Initial velocity, U = 4m/s
Acceleration, a = 0.5m/s²
Time, t = 30 seconds
To find the final velocity, we would use the first equation of motion;
V = U + at
Where;
V is the final velocity.
U is the initial velocity.
a is the acceleration.
t is the time measured in seconds.
V = 4 + 0.5*30
V = 4 + 15
V = 19m/s
Therefore, his final velocity is 19 meters per seconds.
