The golf club is in contact with the golf ball for 1.8 ms and exerts a force of 1500 N on the golf ball. The mass of the golf ball is 0.045kg Calculate the velocity of the golf ball as it leaves the golf club. Velocity m/s Thank you :)

145m/s

Explanation:

Of course

Force x time = Impulse which is a change in momentum. You can then use this to find the velocity (as you know the ball's initial momentum is 0)

1500 x 1.8 x 10^-3 = 0.045v

v = (1500 x 1.8 x 10^-3)/0.045 = 60 ms^-1

Explanation:

The distance the ball travels is directly related to the force that is applied from the head of the golf club, the angle at which the force is applied, gravity, as well as air and wind resistance. The force of the club head on the ball causes the ball to compress and apply an equal amount of force on the club.

use ke=1/2mv^2 rearrange for V

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
