Question

PROBLEM: A car is moving on a straight road with uniform acceleration. Plot the speed-time graph from the
table:
SPEED (m/s) 5
10
15
20
25
30
Time (s)
0
10
20
30
40
50
From the graph determine the acceleration of the car and distance travelled by the car in 50 seconds ​

Answer 1

Answer:

a=0.5m/s^2

s=875m

Explanation:

in v/t graph we get straight line

a=v-u/t

a=30-5/50

=25/50

=1/2

☆a =0.5m/s^2

s=ut+1/2at^2

or

v^2-u^2=2as

30^2-5^2=2(0.5)s

900-25=1s

875=S

☆S=875m
