Which of the following statements are true? check all that apply. the speed of a baseball crossing home plate after being pitched depends on its initial velocity. if thrown at 74 mph, the speed over home plate will be 72.2 mph. if thrown at 50 mph, the speed over home plate will be 44.7 mph.

• the speed of a baseball crossing home plate after being pitched depends on its initial velocity

The speed may be expected to decrease somewhat due to air resistance and/or wind, but there is insufficient information in this problem statement to say precisely what the decrease might be. The one thing you can say is that the final speed has a dependency on the initial speed (as well as a dependency on other factors).

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
