The acceleration of the above velocity-time graph is:
Uniform.
Zero.
Non-uniform.
One.
The velocity-time graph is a curved line. Thus, it gives non-uniform acceleration.
The velocity of a body depends on time according to equation V=20 + 0.1 t2. the body is undergoing
An ant starts from the origin and walks along a straight line. After every second, its position (in mm) is observed by a curious 5-year old. These are his readings:
Position (mm) 0 10 40 100 200
After time (s) 0 1 2 3 4
By looking at this table, which of the following could be a possible description of the ant's motion is
(a) Uniform velocity
(b) uniform acceleration (with non-uniform velocity)
(c) Uniform jerk (with non-uniform accelerator)
(d) cannot be determined (can be any of the above)
The velocity-time graph of a body in motion is a straight line inclined to the time axis. The correct statement is :
(a) velocity is uniform
(b) acceleration is uniform
(c) Both velocity and acceleration are uniform
(d) neither velocity nor acceleration is uniform.
