Question

a truck running at 90 km/h slows down to 72 km/h over a distance of 10m. find the time taken and retardation​

Answer 1

• Areolar connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue.

Answer 2

Answer:

0.44s,11.25m/s^2

Explanation:

u=90*5/18 m/s=25m/s

v=72*5/18=20m/s

S=10m

So now,

v^2-u^2=2aS

400-625=2a(10)

a=-225/20

Retardation=11.25m/s^2(as retardation is negative of acceleration)

Another,

v=u+at

20=25-(11.25)t

t=0.44s
