two bumper cars collide into each other and each caor jolts backwards what law is this isnt it newtons second law?
Yanka [14]
Yes because the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

The voltage across the input terminals of a transformer is 120 V. The primary has 25 loops and the secondary has 50 loops. The v
saw5 [17]

Answer:

240 V

Explanation:

Vp = 120 V

Np = 25

Ns = 50

Vs = ?

Vs / Vp = Ns / Np

Vs / 120 = 50 / 25

Vs / 120 = 2

Vs = 240 V

A 0.032-kg bullet is fired vertically at 230 m/s into a 0.15-kg baseball that is initially at rest. How high does the combined b
gogolik [260]

Answer:

heigth=83.44m

Explanation:

Given data

Baseball mass m₁=0.15 kg

initial speed v₁=0

Bullet mass m₂=0.032 kg

final speed v₂=230 m/s

To find

height h=?

Solution

From conservation of momentum we know that

m_{1}v_{1}+m_{2}v_{2}=(m_{1}+m_{2})v\\ (0.032kg)(230m/s)+(0.15kg)(0m/s)=(0.15kg+0.032kg)v\\7.36+0=0.182v\\v=7.36/0.182\\v=40.44m/s

Now from the conservation of mechanical energy

P.E=K.E\\mgh=(1/2)mv^{2}\\ gh=(1/2)v^{2}\\ (9.8m/s^{2} )h=(1/2)(40.44m/s)^{2}\\ (9.8m/s^{2} )h=(817.7m^{2} /s^{2} )\\h=(817.7m^{2} /s^{2} )/9.8m/s^{2}\\ heigth=83.44m

Two closed containers look the same but when is packed with LED and the other with a few feathers how could you determine which
Rudik [331]
You would want to push both containers, first one and then the other,
with exactly the same strength of push. 

The one that takes off slower (with less acceleration from the same
net force) is the one with more mass.
