Answer:
7.66 m/s²
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 0 mph
Final velocity (v) = 60 mph
Time (t) = 3.5 s
Acceleration (a) =.?
Next, we shall convert mile per hour (mph) to metre per second (m/s). This can be obtained as follow:
Recall:
1 mph = 0.447 m/s
Initial velocity (u) = 0 mph
Initial velocity (u) = 0 × 0.447 = 0 m/s
Final velocity (v) = 60 mph
Final velocity (v) = 60 × 0.447 = 26.82 m/s.
Finally, we shall determine the acceleration of Rihanna as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 26.82 m/s.
Time (t) = 3.5 s
Acceleration (a) =.?
a = (v – u) /t
a = (26.82 – 0) / 3.5
a = 26.82 / 3.5
a = 7.66 m/s²
Thus, the acceleration of Rihanna is 7.66 m/s²
Answer:
Final speed, v = 547.2 m/s
Explanation:
Initial velocity of the bullet, u = 0
Acceleration of the bullet,
Time taken,
Let v is the final velocity of the muzzle. It can be calculated using the first equation of motion as :
v = 547.2 m/s
So, the final speed of the muzzle is 547.2 m/s. Hence, this is the required solution.
This is the solution.
