5.5m/s

Explanation:

Given parameters:

Mass of ball = 22kg

Kinetic energy = 334J

Unknown:

Velocity of the girl = ?

Solution:

Kinetic energy is the energy possessed by a moving body. It is the energy due to the motion of a body.

It is mathematically expressed as;

K.E = $\frac{1}{2} m v^{2}$

Input the values;

334 = $\frac{1}{2}$ x 22 x v²

v² = $\frac{334}{11}$

v² = 30.4

v = √30.4 = 5.5m/s

jamal is playing with magnetic toy vehicles. He has two identical magnetic vehicles (purple and green) on different sides of a c

KengaRu [80]

Answer:

Since potential energy increases with increase in the separation distance, Jamal should move the toy car that will create the largest separation distance. The magnetic force that will act on the vehicles as he moves the cars away from each other will decrease because magnetic force is inversely proportional to the separating distance between the cars.

A 2.00 kg box slides on a rough, horizontal surface, hits a spring with a speed of 1.90 m/s and compresses it a distance of 10.0

oksian1 [2.3K]

Answer:

Explanation:

Given

mass of box $m=2\ kg$

speed of box $v=1.9\ m/s$

distance moved by the box $x=10\ cm$

coefficient of kinetic friction $\mu _k=0.66$

Friction force $f_r=\mu_kN$

$f_r=0.66\times mg$

$f_r=0.66\times 2\times 9.8=12.936 \N$

Kinetic Energy of box will be utilize to overcome friction and rest is stored in spring in the form of elastic potential energy

$\frac{1}{2}mv^2=f_r\cdot x+\frac{1}{2}kx^2$

$\frac{1}{2}\times 2\times 1.9^2=12.936\times 0.1+\frac{1}{2}\times k\times (0.1)^2$

$3.61-1.2936=0.005\times k$

$k=463.28\ N/m$
