Question

7 th question
2nd one and the 3rd

Answer 1

Answer:

(2) acceleration = 100m/s

(3) distance travelled = 200ms

Explanation:

for the second question we will find the area of the square by multiplying time from 5s-10s(5)*20=100m/s

in third part we will find out the area of the whole trapezium

that is 1/2(a+b)h

1/2(5+15)20

=1/2(20)(20)

=200metres
