2. A toy car with a mass of 35g (0.035kg) is moving clockwise around a loop-the-loop (a track in the shape of a circle that causes the toy car to travel along a circular trajectory) with a radius of R- 13cm (0.13m) as depicted in the diagram below. At the point shown (the - on the diagram below) its instantaneous speed (the magnitude of its velocity) is 1.5m/s and its speed is increasing at a rate of 7.1m/s2. (a) (4...

Q3.6 An object moves at a constant speed in a clockwise direction around an oval track. The geometrical center of the track is at point O. When the object is at point P, which arrow shows the direction of the object's acceleration vector? #2 #1 #3 A. #1 (directly away from O) B. #2 (perpendicular to the track) C. #3 (in the direction of motion) D. #4 (directly toward O) E....

An object moves counter-clockwise along the circular path shown below. As it moves along the path its acceleration vector continuously points toward point S. The object speeds up at P, Q, and R. slows down at P, Q, and R. speeds up at P and slows down at R. slows down at P and speeds up at R. speeds up at Q. slows down at Q. No object can execute such a motion. An object moves counter-clockwise along the circular...

5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...

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...

A jogger runs around a circular track of 30 m radius, as shown
in the figure. She runs at constant speed in a clockwise direction
for a few minutes. She completes a round in 40 s.
Using N, S, E, W, cw, or ccw for the direction, compare the
directions and magnitudes of her linear velocity, linear
acceleration, angular velocity and angular acceleration at A, B and
C

4) The diagrams below show a ball swinging on a string. The diagrams show the ball's position at equal time intervals. The first position is when the ball is moving up and left. Copy these into your lab notebook and then draw acceleration vectors for the ball on each one the acceleration points the way you drew it for each diagram. The arrows show the ball's relative speed and direction at each instant and turnaround points have...

angle does this net acceleration vector make with the car's
velocity at this time?
