You kick a soccer ball across a felid. the ball travels across the felid and slowly comes to a stop. Awnser the follwing question about this sceniaro: a. since the ball slowly comes to a stop what does that mean about the accelration of the ball
b. since the ball slowly comes to a stop what does this mean about the net force on the ball as it rolls across the felid? Explain
c. Suppose you were in space away from any opposing forces and you kick the soccer ball. What would happen to the ball?

Astring that is fixed at both ends has a length of 1.05 m. when the string vibrates at a frequency of 91.0 hz, a standing wave with five loops is formed. (a) what is the wavelength of the waves that travel on the string? (b) what is the speed of the waves? (c) what is the fundamental frequency of the string?

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. the cylinder begins to rotate about a vertical axis. then the floor on which the passengers are standing suddenly drops away! if all goes well, the passengers will “stick” to the wall and not slide. clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. part a what is the minimum rotational frequency, in rpm, for which the ride is safe? express your answer using two significant figures. f f = rpm
