A 62.2 kg ice skater moving to the right with a velocity of 2.66 m/s throws a 0.145 kg snowball to the right with a velocity of

Travka [436]

Answer:

Velocity of skater after throwing the snowball is 2.57 m/s

Explanation:

Given :

Mass of skater, M = 62.2 kg

Mass of snowball, m = 0.145 kg

Velocity of snowball relative to ground, v = 39.3 m/s

Consider v₁ be the velocity of skater after throwing the snowball.

According to the problem, initially the velocity of skater and snowball is same. So,

Velocity of skater before throwing snowball, u = 2.66 m/s

Applying conservation of momentum,

Momentum before throwing snowball = Momentum after throwing snowball

(M + m) u = Mv₁ + mv

$v_{1}=\frac{(M+m)u-mv}{M}$

Substitute the suitable values in the above equation.

$v_{1}=\frac{(62.2+0.145)2.66-0.145\times39.3}{62.2}$

v₁ = 2.57 m/s

What type of star has a low temperature and a low luminosity?

Brrunno [24]

Answer:

Explanation:

the higher up on the Main Sequence the star is, the shorter it lives. The smaller main sequence stars have low luminosities and low surface temperatures. These stars take a very long time to fuse hydrogen into helium and will therefore live a very long life.

The term "exfoliation dome" is best applied to ________. the term "exfoliation dome" is best applied to ________. bryce national

BlackZzzverrR [31]

An exfoliation dome is a geological structure wherein it is primarily when the overburden of a surface gets removed by erosion, thus leading to rock relaxation. In addition, the term would be best applied to the national landmark of Yosemite National Park wherein the place has one of the best waterfalls in California.

What’s the force of a pitching machine on a baseball? Baseballs pitched by a machine have a horizontal velocity of 30 meters/sec

Leya [2.2K]

The acceleration of the baseball is:
$a= \frac{v_f-v_i}{\Delta t}$
where $v_f$ and $v_i$ are the final and initial speed of the ball, and $\Delta t$ is the time interval in which the force acted.

Replacing the numbers, we get
$a= \frac{30 m/s-0m/s}{0.5 s}=60 m/s^2$
And at this point, we can use Newton's second law F=ma to find the value of the force of the pitching machine:
$F=ma=(0.15 kg)(60 m/s^2)=9 N$
