Question

What is the initial upward velocity of a projectile fired at an angle of 40 m/s at an angle of 20o? A) 2 m/s B) 13.68 m/s C) 14.55 m/s D) 38 m/s

Answer 1

Answer: I choose A

Step-by-step explanation:

Answer 2

Find the upward velocityt by multiplying the speed by the cos of the angle.

= 40 x cos(20) = 37.588 m/s

Round to 38 m/s

The answer is D.
