lonnie pitches a baseball of mass 0.02kg. The ball arrives at home plate with a speed of 40 m/s and is batted straight back to L

onnie with a return speed of 60 m/s. If the bat is in contact with the ball 0.050 s, what is the impulse experienced by the ball?

Answer:

I=2 kg.m/s

Explanation:

The impulse is defined as the change of momentum:

I=p_f-p_o\\I=m*v_f-m*v_o\\I=0.02kg*[(-60m/s)-40m/s]\\I=2kg.m/s

We took the final velocity as negative since it is going on the opposite direction of the intial motion of the ball.

A young woman walks up 55 steps to the top of a water slide. She slides
navik [9.2K]

Answer:

potential energy PE = M g h

KE at bottom = 1/2 M V^2

Regardless of the slope of the slide the change in energy is the same

1/2 V^2 = g h

V = (2 g h)^1/2 = (2 * 9.8 m/s^2 * 10 m)^1/2 = 14 m / s

Perhaps the question says that h = 55 * .1 = 5.5 m

Then V = (2 * 9.8 * 5.5) = 10.4 m/s

How do you decrease the reaction force felt on the egg if its change in momentum, and therefore total impulse, stays
Ivenika [448]

Answer:

Hey, how you doing.

I think (key word think, i haven't done this test) that you would make the egg smaler and make it go faster, so that the atomic bonds are stronger.
