A movie director wants a scene in which a car appears to fly off a cliff at $50 \;\mathrm{mph}.$ To simulate this, the director will make a $1/100$ scale model of a car and cliff, and have the model car fly off the model cliff. By what factor should the film be sped up or slowed down in order to look realistic, and what should the real speed of the toy car be as it approaches the cliff

B) erini just took the test and it is correct

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

A=v^2/r solve for r hope that
