the distance moved by a student at a different intervals of time, while walking to school, is given in the - Science - Motion

Question

the distance moved by a student at a different intervals of
time, while walking to school, is given in the table below
t(s) 0 10 20 30 40 50
s(m) 0 15 30 45 30 60
draw speed time graph for the motion of the student what does
the shape of the graph suggest about the type of motion?

Since, speed = Distance/ Time
Therefore, the speed for the case 1 at t= 0 and s = 0 m will be
v1 = 0/0 = 0 m/s
Similarly,speed for the case 2, 3, 4, 5 and 6 will be 1 5 m/s, 1 5
m/s, 1 5 m/s,0 75 m/s and 1 2 m/s respectively It is also shown in
the table given below :

Time (s)
0
10
20
30
40
50

Distance (m)
0
15
30
45

60

Speed (m/s)
0
1 5
1 5
1 5
0 75
1 2

The speed - time graph will be as shown :

From graph, we find that the from point A to point B, the student
moves with constant speed and from point O to A, he is moving with
positive acceleration

Time (s)	10	20	30	40	50
Distance (m)	15	30	45	30	60
Speed (m/s)	1.5	1.5	1.5	0.75	1.2
