Can a net force be applied to an object and still have the object maintain constant speed. explain. a) no, a net force accelerates an object. b) no, a net force will always slow down the object. c) yes, a net force does not always acelerate an object. d) yes, if the net force is perpendicular to the motion of the object it will only change its direction.

Yes, if the net force is perpendicular to the motion of the object it will only change its direction. In this case the object can experience constant speed circular motion. Its D

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
