Answer:

The answer is 0.12.

Explanation:

The least number of significant digits in the problem determines the number of significant digits in the answer in any multiplicantion/division problem. So for 15.0/124 there would be 2 significant digits in the answer since 15.0 has the least number of sig digs.

Kryger [21]

Answer:

Vf = 41.6 [m/s].

Explanation:

To solve this problem we must use the equations of kinematics.

Vf² = Vo² + (2*g*y)

where:

Vf = final velocity [m/s]

Vo = initial velocity = 0

g = gravity acceleration = 9.81 [m/s²]

y = height = 88.2 [m]

Note: The positive sign of the equation tells us that the acceleration of gravity goes in the direction of motion.

Vf² = Vo² + (2*g*y)

Vf² = 0 + (2*9.81*88.2)

Vf = (1730.48)^0.5

Vf = 41.6 [m/s]

1. Which of the following equations can be used to directly calculate an object s momentum, p?

Taya2010 [7]

Answer:

p = mv

Explanation:

The momentum of an object is given by the equation:

$p=mv$

where

m is the mass of the object

v is the velocity

Since velocity is a vector, it follows that momentum is a vector as well, therefore it has a magnitude and a direction (the same as the velocity).

The SI unit of the momentum is $kg \cdot m\cdot s^{-1}$

An important law related to the momentum is the law of conservation of momentum, which states that for an isolated system (= zero net external force on it), the total momentum of the system is conserved.
