The potential energy of an apple is 19.6 J, and it is 8 m above the ground. The mass of the apple is _____ kg
Crazy boy [7]
We know, U = mgh
Substitute the known values, 
19.6 = m * 9.8 * 8
m = 19.6 / 78.4
m = 1/4

In short, Your Answer would be 1/4 Kg

Hope this helps!

Which trial’s cart has the greatest momentum at the bottom of the ramp?
Licemer1 [7]
The momentum of each cart is given by:
p=mv
where
m is the mass of the cart
v is its velocity (at the bottom of the ramp)

To answer the problem, let's calculate the momentum of each of the 4 carts:
1) p=(200 kg)(6.5 m/s)=1300 kg m/s
2) p=(220 kg)(5.0 m/s)=1100 kg m/s
3) p=(240 kg)(6.4 m/s)= 1536 kg m/s
4) p=(260 kg)(4.8 m/s)=1248 kg m/s

Therefore, the cart with greatest momentum is cart 3, so the right answer is
<span>- trial 3, because this trial has a large mass and a large velocity</span>

If the rotation of a planet of radius 5.32 × 106 m and free-fall acceleration 7.45 m/s 2 increased to the point that the centrip
leonid [27]

Answer:

v = 6295.55 m/s

Explanation:

Given that,

The radius of a planet, r=5.32\times 10^6\ m

The free fall acceleration of the planet, a = 7.45 m/s²

We need to find the tangential speed of a person standing at the equator.

Also, the centripetal acceleration was equal to the gravitational acceleration at the equator.

We know that,

Centri[etal acceleration,

a=\dfrac{v^2}{r}\\\\v=\sqrt{ar}\\\\v=\sqrt{5.32\times10^6\times 7.45}\\\\v=6295.55\ m/s

So, the tangential speed of the person is equal to 6295.55 m/s.
