Jim got 2 out of 5 questions correct on his test. Which is equivalent to 2/5?

1 answer:

8 0

Hey there, 2 out of 5 is 2/5. There are a lot of fractions that is equivalent to 2/5, so I am only going to give you 3, 2/5=4/10, 6/15, and 8/40, 2*2=4 and 5*2=10.

Answer: 29.2

Step-by-step explanation:

The lengths of the two longer legs are both $\sqrt{8^2 + 4^2}=\sqrt{80}$

The lengths of the two shorter legs are both $\sqrt{4^2+4^{2}}=\sqrt{32}$

So $P=2\sqrt{80}+2\sqrt{32} \approx 29.2$

What net force will make a 5 kg bowling ball accelerate by 1.5 m/s square 2?

s2008m [1.1K]

In pure translation or in roll without slip?

In pure translation, just use Fnet = m*a. Fnet = 7.5 Newtons

In roll without slip it has effectively more inertia than 5 kilograms. The effective inertia can be found as:

m_effective = m + I/r^2

For a uniform solid sphere, I = 2/5*m*r^2

So m_effective = 7/5*m

To make a 5 kg bowling ball accelerate at 1.5 m/s^2 in roll without slip, it requires Fnet = 10.5 Newtons, and this ASSUMES that all forces causing the net force on it have lines of action through its center of mass (most common case).
