Please answer this physics question im desperate!! 20 POINTS AND BRAINLIEST!!

Answer 1

Answer:

At any time on a distance vs time graph the slope of the line is speed of the object at that  particular time:

Line C: The slope is zero so the object is not moving (d is a constant zero)

Line A: The slope is a constant: at any time d = K t where K is constant

             and v = d / t = K        so the object is moving with constant speed

Line B: the object is accelerating since the instantaneous speed of the object at any time s given by d / t  at that time - since the slope is increasing with increasing  time the speed is increasing as time increases and the object is accelerating

On a speed vs time graph (actually a graph of slope of the distance vs time graph.

Line C: similar to C above since the speed is always zero.

Line A: the slope of the graph must be zero since the speed is constant and the graph is just a horizontal line with the y-coordinate at the value of the constant speed as time increases

Line B: not enough information to determine if the acceleration is constant, but it could be, and then you get a graph similar to A above because the slope of the speed vs time is a measure of the acceleration at any particular time

Q.1)

OBJECT A = UNIFORMALY ACCELERATED MOTION

ONJECT B = NON UNIFORMALY ACCELERATED MOTION

OBJECT C = UNIFORM MOTION
