Snowballs are thrown with a speed of 13 m/s from a roof 7.0 m above the ground. snowball a is thrown straight downward; snowball b is thrown in a direction 25o above the horizontal. when the snowballs land, is the speed of a greater than, less than, or the same speed of b? verify your answer by calculation of the landing speed of both

Speed of both the ball will be same

Explanation:

For snow ball A

Initial velocity u = 13 m/sec

Acceleration due gravity

According to third law of motion

So

v = 17.5 m/sec, here v is final velocity

For snow ball B

Initial velocity v = 13 m/sec

Angle with horizontal = 25°

Horizontal component of velocity

Vertical component of velocity

So resultant velocity of ball B

So speed of both the ball will be same

d

explanation:

i think the answer is d. but im not sure!

the closer the planet is to the sun, the larger the gravity
