Question

An object is launched with an angle of 25 upward with the horizontal. The initial velocity of the object is 20 m/'s in a direction making. What is the vertical velocity of object at the maximum height reached by the object? 0.00 O 15.11 O 18.40 O 21.20

Answer 1

When any object is projected with a vertical angle, it always undergoes retardation due to the earth's gravity.

The initial velocity in the vertical direction will be

$U^{_{x = U sin\Theta }}$

And due to the gravitational acceleration acting downward the velocity get decreased and finally become 0m/s at the highest point of the projectile motion.

There the answer is option A, 0.0m/s
