Question

A car is moving on a straight road at a uniform acceleration. The velocity of the car at different times
is given below. Draw its velocity time graph and calculate its acceleration and also find out the
distance covered by it in 30 seconds,
t Time (s)
10 20
30
40 50
v speed (m/s) 5 10 15 20 25 30
0
In the following fique​

Answer 1

Answer:

(i) Acceleration of the car = slope of AB=

10−0

24−4

=
