From Newton's third law, the force of the floor on the ball and the force of the ball on the floor are equal in magnitude and in opposite directions. Between the floor and the ball, which received most of the collision energy?
The ball received most of the collision energy and the force of the floor on the ball is in the upward direction.
The ball received most of the collision energy and the force of the floor on teh ball is in the doward direction.
The floor received most of the collision energy and the force of the ball on the floor is downwards.
The floor received most of the collision energy and the force of the ball on the floor is upwards.
Nitrogen and oxygen in their liquid states have densities only 0.80 and 0.90 that of water. Atmospheric pressure is due primarily to weight of nitrogen and oxygen gas in the air. If atmosphere liquefied would its depth be greater or less than 10.30 m..
In a ballistics test, a 23-g bullet travelling horizontally at 1300 m/s goes through a 40.0 cm-thick 450-kg stationary target and emerges with a speed of 900m/s. The target is free to slide on a smooth horizontal surface.
A parallel beam of light from a He-Ne laser, with a wavelength of 662nm, falls on two very narrow slits 0.050 mm apart. How far apart are the fringes in the center of the pattern if the screen is 2.5m away.
The longest recorded pass in an NFL game traveled 86 yards in the air from the quarterback to the receiver.Assuming that the pass was thrown at the optimal 45 angle, what was speed at which the ball left the quarterback's hand.
You are a professional frontier re-enactor who specializes in making lead shot. To do this you put 1.3 kg of ice into 1.3 kg of water, both at 0 C, into an insulated bucket.
When kicked, the ball leaves the ground with a speed of 29.0 m/s at an angle of 51° to the horizontal. Explain by how much does the ball clear or fall short of the crossbar?
What is the electric flux through the circle when its face is perpendicular to the field lines?
A gymnast of mass 69.0 kg hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 for the acceleration of gravity.
Find the distance between the centers of the spheres.
There are many estimates of the number of stars in the universe. One estimate is that there are 1010 stars in the Milky Way galaxy, and that there are 1010 galaxies in the universe.
An object consists of a ball of weight W glued to the end of a uniform bar also of weight W. if you release it from rest, with the bar horizontal.
A certain freely falling object requires 1.10s to travel the last 32 m before it hits the ground. From what height above the ground did it fall.
