A block of wood

Physics
1 answer:
Feliz [49]2 years ago
3 0

Answer:

Explanation:

conservation of momentum

m(u) + M(0) = (m + M)v

u = (m + M)v/m

u = (0.250 + 1.35)(11.9) / 0.250

u = 76.16

u = 76.2 m/s

That's a fairly massive, and slow, bullet.

joja [24]

Answer:17.44A

Explanation: Current density=I/Area

Area is given by 2.79mm^2=2.79×10^-6m^2

Current=I=current density ×Area=6.25×10^6 ×2.79×10^-6=17.44A

Avi, a gymnast, weighs 40 kg. She is jumping on a trampoline that has a spring constant value of 176,400 . If she compresses the
viva [34]

<u>Answer</u>

9 m


<u>Explanation</u>

The energy stored in a spring is given by:

Energy = 1/2 k²e

Where e is the compression and k is the spring constant.

 Energy = 1/2 × 176,400 × 0.2²

              = 3,528 N

The same energy will then be converted to potential energy given by:

Energy = mgh

Where m is the mass, g is the gravity and h is the height above the ground.

Energy = mgh

3,528 = 40 × 9.8 × h

3,528 = 392h

h = 9 m
