A Thomson's gazelle can run at very high speeds, but its acceleration is relatively modest. A reasonable model for the sprint of

a gazelle assumes an acceleration of 4.2 m/s2m/s2 for 6.5 ss , after which the gazelle continues at a steady speed. What is the gazelles top speed?

Answer:

v = 27.3 m/s

Explanation:

Given that

Acceleration ,a= 4.2 m/s²

Time ,t= 6.5 s

Lets take the maximum speed gain by Thomson's= v

We know that ,if acceleration is constant then the speed v is given as

v= u +  a t

v=final speed

u=initial speed

a=acceleration

t=time

Here the initial speed of Thomson's ,u = 0 m/s

Now by putting the values in the above equation we get

v= 0 + 4.2 x 6.5 m/s

v = 27.3 m/s

Therefore the maximum speed gain by Thomson will be 27.3 m/s.

A teacher performing demonstration finds that a piece of cork displaces 23.5 ml of water. The piece of cork has a mass 5.7 g. Wh
Sedbober [7]

Answer: 0.24g/ml

Explanation:

Given that:

Volume of water displaced = 23.5 ml

Mass of cork = 5.7 g

Density of the cork = ?

Recall that density is obtained by dividing the mass of a substance by the volume of water displaced.

i.e Density = Mass/volume

Density = 5.7g /23.5ml

Density = 0.24g/ml

Thus, the density of the piece of cork is 0.24g/ml
