<< David is swinging his 0.5 m long sling and exerting a centripetal force of 1,250 N. Soon he will hurl the 250 g
rock in the sling at Goliath. What is the velocity of the
rock as it leaves the sling?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied. true or false

Which expression allows you to determine the mechanical advantage of an inclined plane? a. height of plane / input force b. length of plane / input force c. length of plane / height of plane d. height of plane / length of plane

Why are graphs useful when interpreting data
