A10 kg object resting on a horizontal frictionless surface is subjected to two forces. f1= 30n directed east and f2= 50n directed west. find (a.) acceration; and (b.) displacement after 10 seconds starting from rest.​

    A car travels 35.0 mph north for 1.00 hour, then 40.0 mph east for 0.0500 hour, and finally 50.0 mph northeast for 2.00 hours. Calculate the average speed. v = mph

    We have the following data:

    * velocity (in mph)

    (V1) = 35.0 mph

    (V2) = 40.0 mph

    (V3) = 50.0 mph

    * weights for the time (in hours)

    (T1) = 1.00 hour

    (T2) = 0.0500 hour

    (T3) = 2.00 hours

    We apply the data to the weighted average formula to find the average speed, let us see:

    Weight\:Average = \dfrac{V_1*T_1+V_2*T_2+V_3*T_3}{T_1+T_2+T_3}

    Weight\:Average = \dfrac{35.0*1.00+40.0*0.0500+50.0*2.00}{1.00+0.0500+2.00}

    Weight\:Average = \dfrac{35+2+100}{3.05}

    Weight\:Average = \dfrac{137}{3.05}

    Weight\:Average = 44.91803279...

    \boxed{\boxed{Weight\:Average = 44.92\:mph}}\Longleftarrow(Average\:Speed)\:\:\:\:\:\:\bf\purple{\checkmark}

    The Average Speed is approximately 44.92 mph

    Good Day


    You drop your cellphone while in the bathroom in front of the mirror while the water is running is in the sink below. If you are 0.45meters above the sink,how long do you have before your cell phone is a gonner.

    Given Data:

    Vi (initial velocity)  =  0 m/s (at top)

    d (distance) = 0.45 m

    t (time) =  unknown

    a (acceleration) = 9.8 m/s²


    We can use the formula  t = √d/1/2a  since Vi = 0 m/s

     t = √d/1/2a

       = √ 0.45 m / 1/2(9.8 m/s²)


       = √ 0.45 m / 4.9 m/s²

       = √0.0918 s²

       = 0.303 s

    You have  0.303 seconds or 0.30 seconds or 0.3 seconds
