Question

PLEASE HELP ME TIMED TEST!!!

Answer 1

Explanation:

$\boxed{\sf{K.E = \dfrac{1}{2} \times m \times v^2}}$

• Here, K . E or Kinetic Energy is given as 14 J
• Here, mass is 17 kg

Let's Do!

$\boxed{\sf{14 = \dfrac{1}{2} \times 17 \times v^2}}$

$\boxed{\sf{\dfrac{14 \times 2}{17} = v^2}}$

$\boxed{\sf{ \sqrt{\dfrac{14 \times 2}{17}}= v}}$

So, 1.283 m/s is the required answer.

Answer 2

Answer:

56

Explanation:

I just want the points to be completely honest with you.
