Natasha_Volkova [10]

Answer:

17.04%

Explanation:

Actual Value = 173.1

Measured Value = 143.6

Percent error is obtained using the equation;

Percent error = (Measured - Actual) / Actual ]* 100

Percent error = [ (143.6 - 173.1) / 173.1 ] * 100

The absolute value of (Measured - Actual) is taken,

Percent Error = [29.5 / 173.1 ] * 100

Percent Error = 0.1704 * 100 = 17.04%

Answer:

100N

Explanation:

Given parameters:

Mass of the bowling ball  = 20kg

Acceleration  = 5m/s²

Unknown:

Amount of force applied  = ?

Solution:

To solve this problem, we apply newton's second law of motion.

    Force  = mass x acceleration

Now insert the parameters and solve;

   Force  = 20 x 5  = 100N
