A Bumper Car Is Moving at Constant Velocity When Another

question 110

Multiple Choice

A bumper car is moving at constant velocity when another bumper car starts to push on it with a constant force at an angle of 60 degrees with respect to the first car's initial velocity. The second bumper car continues pushing in exactly that direction for some time. What is most likely to happen is that

• A) the first car will stop moving.
• B) the first car will move in the direction of the force.
• C) the first car's velocity will increase in magnitude but not change direction.
• D) the first car's velocity will gradually change direction more and more toward that of the force while increasing in magnitude.
• E) the first car's velocity will gradually change direction more and more toward that of the force while decreasing in magnitude.
