A ball has a horizontal velocity of 200 m/s when it begins to fall from a height of 490m.
• What time will it take to land?
• What will be it's Range?
A. Time = 100 s
Range = 490 m
B. Time = 10 s
Range = 2000 m
C. Time = 10 s
Range = 490 m
D. Time = 100 s
Range = 200 m

as technology advances, new experiments often expose problems in accepted theories. c

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

f=ma newton

f=100x2.5=250n
