Answer:
9.17 m/s
Explanation:
Impulse = change in momentum
FΔt = mΔv
(166 N) (0.39 s) = (7.06 kg) Δv
Δv = 9.17 m/s
We know, density = mass /volume
Here, m = 10 g
v = 2.5 mL = 2.5 cm³
Substitute their values,
density = 10/2.5
<span>d = 4 g/cm³
</span>
In short, Your Answer would be <span>4 g/cm³</span>
Hope this helps!
Answer:
Mass velocity and radius are all related to centripetal force
Explanation:
By frequency of its rotation and the radius of the circular path along which objects moves
Answer:
KE= 1/2 * mass * Velocity^2
Explanation:
1/2 * 72.0kg* 79^2 m/s = 224676 J
Acceleration is the change in velocity
