In deep space, an object is traveling at constant speed in a straight line. Then it is observed to change its direction of travel. What can the server condude? A. The forces acting on the object must have changed.
B. The object's mass must have changed.
C. The object's speed must have changed.
D. Enough time had elapsed to show the object down,

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

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
