Momentum
1. An ostrich with a mass of 146 kg is running to the right with a velocity of
17 m/s. Find the momentum of thc ostrich.

2482 Kg.m/s

Explanation:

Momentum is a product of mass of an object and its velocity with consideration to the direction of velocity and expressed as, p=mv where m represent mass of the ostrich and v is the velocity in m/s, p is momentum.

Substituting the mass of ostrich with 146 kg and the velocity as 17 m/s then the momentum of the ostrich is equal to

P=146*17=2482 kg.m/s

Therefore, the momentum of ostrich is equal to 2482 kg.m/s

the first, second, and fifth options

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
