There is a 30 cm section of friction with a coefficient of friction 0.3 on an otherwise frictionless ramp. There is a spring of K = 40 and N/m at the end of the flat section. I dropped a 0.1 kg ball from a position on the ramp with a vertical height of 50 centimetres. Where (exactly) on the ramp will the ball stop?

If football was tossed in air without gravity or friction the ball would go into space

Ireally don’t know

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.
