I want to create a plot of a given function for all x values between negative infinite to negative R (for some given R value). How do I create an array for x so that my plot will include all the x values?

Does anyone know how I can do 28, 30, and 32, reproduced below? 28. A person pushes a 14.5-kg lawn mower at constant speed with a force of 88.0 N directed along the handle, which is at an angle of 45.0 degrees to the horizontal. Calculate (a) the horizontal retarding force on the mower, then...

are you still there stunner5000pt ?

Is this right now? Vfinal ^2 = vinitial ^2 + 2ad (0)^2=(45.0m/s)62 + 2a(.11m) 0m/s=2025m/s + .22a a=-9205m/s^2 F=ma F=(0.140kg)(-9205m/s^2) F=-1289N right?

oh so vfinal should be 0? because it says its at rest when it hits the mitt

it bounces back .11 meters

what should it be?

v initial i put is 45 m/s, v final is 45 m/s distance is .11m

i meant to calculate the acceleration

i used the formula vfinal^2=vinitial^2 + 2ad to calculate the velocity, and got 0. Is this correct? if so, the force would end up being 0?

It says the baseball recoils backward 11.0 cm. Is that the distance?

8. What average force is needed to accelerate a 7.00-gram pellet from rest to 175 m/s over a distance of 0.700 m along the barrel of a rifle? 9. A fisherman yanks a fish out of the water with an acceleration of 4.5 m/s^2 using very light fishing line that has a "test" value of 22 N. The...
