Please help.

Alex787 [66]

Explanation:

mathematically,

$kinetic \: energy \: = \frac{1}{2} m {v}^{2}$

where m= mass

and v=velocity

given that,

kinetic energy=493900J

mass =5040kg

making velocity the subject

$v = \sqrt{ \frac{2 \times kinetic \: energy}{mass} }$

substitute their values in the formula

$v = \sqrt{ \frac{2 \times 493900}{5040} }$

$v = \sqrt{ \frac{987800}{5040} }$

$v = \sqrt{196}$

$v = 14m {s}^{ - 1}$

Thus the velocity is 14meters per second

A 1000 kg boat starts at rest and accelerates to 10 m/s in 2 seconds. How fast does the boat accelerate?

Hitman42 [59]

Answer:

$5 m/s^2$

Explanation:

The acceleration of an object is given by

$a=\frac{v-u}{t}$

where

v is the final velocity

u is the initial velocity

t is the time it takes for the velocity to change from u to v

For the boat in the problem,

v = 10 m/s

u = 0

t = 2 s

Substituting, we find the acceleration

$a=\frac{10-0}{2}=5 m/s^2$
