Through slow on land the leather back turtle holds the record for the fastest water speed of any reptile. the largest leather back yet discovered could swim at a speed of 9. 78 m/s. if it's ke was 60, 800. 0j, what's the mass

1271.32 kg

Step-by-step explanation:

Given: The speed of turtle with largest leather back= 9.78 m/s

It's Kinetic energy = 60800 joules

We know that with mass 'm' and speed 'v', the formula kinetic energy is given by

Hence, the mass of turtle= 1271.32 kg

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
