Amotorcycle has a magnet attached to the rim of its front wheel. the front tire has a diameter of 60 cm. a magnetic pickup is attached to the front forks and receives an electronic pulse each time the magnet passes by. how far has the motorcycle traveled when the pickup has received 10 pulses?

The speed was not exceeded so it was slow

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.
