Question

pls pls pls pls help me​

Answer 1

Answer:

Average Speed =total distance /total time

=20+16/2+2=36/4

=9m/sec

Answer 2

Explanation:

22. average speed= total distance/total time taken

av speed =20+16/2+2

=36/4

=9 m/s is ans of ques22....

23. SI unit of force is equals to kgm/s²

F =2N

U=2m/s

V=5m/s

t=10s

we know that,

F =ma --------(1)

:- a= v-u/t

a=5-2/10

a=3/10 m/s²

putting value of"a" in equation (1),we get:

2=m×3/10

2=3/10m

m=2×10/3

m=20/3

m=6.6kg
