10. A toy car on a track starts from rest at the top of a 2.3 meter hill and rolls down. The car then goes
up a ramp and flies off the track (see diagram below). If the end of the ramp is 0.91 meters high, at
what speed does the car leave the track?
2.3 m
0.91 m

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048

v patient student

the answer is b i think

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
