Look at the triangle below.

slega [8]

Answer:

a = 32.48538491

b = 25.59883264

Step-by-step explanation:

To find the length of a, use the sine function:

$sin\alpha = \frac{opposite}{hypotenuse}$

$sin 38 = \frac{20}{a} \\a = \frac{20}{sin38}\\a = 32.48538491$

To find the length of b, use tangent:

$tan\alpha = \frac{opposite}{adjacent}$

$tan 38 = \frac{20}{b} \\b = \frac{20}{sin38}\\b = 25.59883264$

An archer shot a 0.06 kg arrow at a target. The arrow accelerated at 5,000 m/s2 to reach a speed of 50.0 m/s as it left the bow.

laila [671]

Answer:

300 N

Explanation:

The net force acting on the arrow is given by Newton's Second Law:

$F=ma$

where

m = 0.06 kg is the mass of the arrow

a = 5,000 m/s^2 is the acceleration of the arrow

Substituting the numbers into the equation, we find

$F=(0.06 kg)(5,000 m/s^2)=300 N$
