At what speed do a bicycle and its rider, with a combined mass of 120 kg , have the same momentum as a 1800 kg car traveling at 5.6 m/s ?

The momentum of the car is equal to:

We need to find the new speed v at which the new system (bycicle+rider) have same momentum p of the car. The mass M of the new system is M=120 kg. Using the value of momentum we found previously and the same formula for the momentum, we find

So, the speed of the bycicle must be 84 m/s.

Idon't know it i just need my points lol

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
