Part E From your observations about the horizontal and vertical component of position, velocity and acceleration, do you think taking
"Legs" of the snowboarder as reference point for plotting the motion is a good option for describing the snowboarder's
projectile motion?

For Plato.

An object of dimensions 50 cm x 40 cm x 0.20 cm has a mass 60g. find its density in g/cm3 and kg/ m3

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

Abumper car with a mass of 250 kg is traveling at a speed of 4 m/s. this bumper car collides and sticks to a second bumper car with a mass of 250 kg, which is initially at rest. what is the final speed of these two bumper cars after the collision, assuming they remain stuck together?
