Explanation:
Answer:
C) 40,000 Joules
Explanation:
½(1000)10² - 10000 = 40000
Explanation
(m) is measured in kilograms (kg)
<h2>(F) is measured in newtons (N)</h2>
<h3>acceleration (a) is measured in metres per second squared (m/s²)</h3>
Answer:
-387883.3 m/s²
0.000286168546055 seconds
Explanation:
t = Time taken
u = Initial velocity = 370 m/s
v = Final velocity = 259 m/s
s = Displacement = 9 cm
a = Acceleration
The acceleration of the bullet is -387883.3 m/s²
The time taken is 0.000286168546055 seconds
