Answer: 21 kg x m/s
Momentum can be found using the equation p = mv, or momentum = mass times velocity.
Therefore, to find the momentum of the bowling bowl, you can plug the mass and velocity values into the equation to get p = (7kg)(3m/s)
Solve the equation to get a momentum of 21kg x m/s
I hope I could help :)
Answer:
a) 0.0324 rad/s²
b) 2.01 rad/s , the final angular speed gets doubled
Explanation:
w₀ = initial angular speed = 0 rad/s
w = final angular speed = 0.16 rev/s = 0.16 (6.28) = 1.005 rad/s
t = time interval = 31 s
α = angular acceleration
final angular speed is given as
w = w₀ + α t
1.005 = 0 + α (31)
α = 0.0324 rad/s²
b)
After the acceleration is doubled
α' = 2 α = 2 (0.0324) = 0.0648 rad/s²
w' = final angular speed
w'₀ = initial angular speed = 0 rad/s
final angular speed is given as
w = w₀ + α t
w = 0 + (0.0648) (31)
w = 2.01 rad/s
yes the final angular speed gets doubled
This may help if you know which alleles are dominant and recessive.
