Question

Suppose that the force applied to the object were twice as large as that of previous problem. Match the appropriate Velocity, Acceleration and Force vs time graphs in the figure. Note: the graphs on this problem and the last have exactly the same scales. grane F G A H E 4 3 1 0 5 4 3 2 1 Time(s) Time(s) 1. F Velocity 2.A 3.1 Acceleration 4.G Force 5.D 6.

Vel/accel/force a LU Vel/accel/force QUESTION 5 An object can move in either direction along a horizontal line (the + position axis). Assume that friction is so small that it can be neglected. Which graph corresponds to the force applied to the object that would produce the motion described? A 1 2 3 4 5 Time(s) The object moves away from the origin with a constant velocity 1. E 2.D The object moves toward the origin with a constant velocity. 3. B 4.A The object moves away from the origin with a steadily increasing velocity (constant acceleration.) 5. C Force

Answer 1

5.) If the object has constant velocity, then the net force on it is zero.

So, for part 1 and 2 answer will be C.

for 3, constant acceleration means, a constant non-zero force, also away from the origin implies +ve force, B.

Part II

B- velocity

G- acceleration

F- Force

Force is ma so, its slope is greater than that of the acceleration graph.
