two balls are at the same height. One ball is dropped and the other initially moves horizontally, as shown in the figure above. After one second, which ball has fallen the greatest vertical distance?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.

The upward force acting on the wing of a airplane in flight is known as the "lift" force. (d)
