Ahorizontal pipe narrows from a radius of 0.250 m to 0.1000 m. if the speed of the water in the pipe is 1.00 m/s in the larger-radius pipe, what is the speed in the smaller pipe? given the density of water is 1000 kg/m3 , what is the mass flow rate, kg/s, of the water through the pipe?

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

Abatter hits a 0.140-kg baseball that was approaching him at 30 m/s and, as a result, the ball leaves the bat at 40 m/s in the reverse of its original direction. the ball remains in contact with the bat for 2.0 ms. what is the magnitude of the average force exerted by the bat on the ball?

If a person whirls an object horizontally in a counter clockwise direction and the string breaks at point p as shown, what path will the rock follow?
