Abaseball pitcher throws a fastball horizontally at a speed of 42.0 m/s. ignoring air resistance, how far does the ball drop between the pitcher’s mound and home plate, 60 ft 6in away? 0.945 m 2.15 m 1.02 m 0.382 m a rescue plane spots a person floating in a lifeboat 55 m directly below and releases an emergency kit with a parachute. the package descends with a constant vertical acceleration of 6.91 m/s. if the horizontal speed of the plane was 70.6 m/s, how far is the package from the lifeboat when it hits the waves? 225 m 1.27 km 323 m 282 m

#1

Pitcher throws a ball with speed 42 m/s

Now we need to find the distance that it dropped when it covered a distance of 60 ft and 6 inch

now the time taken by the ball to cover this distance

now in the same time we need to find the fall of the ball so here we will use kinematics

so it will fall by 0.945 m in the given time

#2

package is dropped directly above the boat position

So it will freely fall down on the water surface

so here we can use kinematics to find the time of drop

now we will say that in this time package will cover horizontal distance with speed 70.6 m/s

so it will fall 282 m away from the boat

the answer is b, have negligible mass
