if an object has acceleration pointing to the right. What is the direction of the velocity?
An object moving with uniform acceleration has a velocity of 11.0 cm/s in the positive x-direction when its x-coordinate is 3.06 cm. If its x-coordinate 3.05 s later is −5.00 cm, what is its acceleration?
Two students are discussing what determines the direction of an object’s velocity change arrow. Student A says: The velocity change arrow is in the same direction as the velocity of the object. Student B says: The velocity change arrow is independent of the velocity of the object. You have the following equipment: spring scale, mass, stand, motion sensor, stopwatch, metre stick What kind of experiment to do to prove one of the student is wrong? My answer: I believe student...
Answer the following questions: a) In the picture above, the velocity is pointing in the [Select ] direction and the acceleration is pointing in the Select ] direction. Therefore the skateboarder is Select ] d) In the picture above, the velocity is pointing in the [Select ] ' | directon and the acceleration is pointing in the [Select ] direction. Therefore the skateboarder is Select ] b) In the picture above, the velocity is pointing in the Select] in the...
with reason please. Velocity and Acceleration Vectors An object is moving with an initial velocity along the x-axis and a constant acceleration in the second quadrant of the x-y plane as shown. Which one of the following statements about the subsequent motion of the object is true? (a) The velocity of the object never changes magnitude. (b) The velocity of the object never changes direction. (c) The direction of the velocity of the object is never the same as that...
Can the velocity of an object stop and reverse direction when its acceleration is constant? Explain with 100 words or less

If a wheel has an angular acceleration in the clockwise direction as seen by an observer in what direction is the torque pointing? a. Up as seen by the observer b. To the right as seen by the observer c. Away from the observer d. Towards the observer
c. It has tangential (linear) acceleration that points in the same direction as the velocity, and a decreasing centripetal acceleration d. It has tangential (linear) acceleration that point opposite the velosity, and a constant centripetal acceleration QUESTION 3 A 53.5 kg parachutist jumps from an airplane and falls to Earth with a drag force proportional to the square of the speed, R-CV. Take C -0.220 kg/m (with the parachute closed) and C - 22.0 kg/m (with the chute open). What...
An object has zero acceleration in the x-direction. In the y-direction, its acceleration must be which of the following? 1-Positive 2- Zero 3- negative 4- Any of the previous answers is possible.
An object is moving in the x direction only and its acceleration is given by a(t) =-7 m/s^5 t^3. If its initial velocity is 17 m/s in the x direction, what is the displacement of the object, in meters, when the object stops? Include a negative sign if the displacement is in the -x direction.
