Sally and her friend are having a heated argument over the velocity-time graph from the ramp lab. Sally says that the positive linear slope in this graph indicates constant velocity. Write a CER conclusion, using information gathered during the Ramp Lab, explaining whether Sally is correct in her understanding.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

unlike poles attract

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
