Proposition.
You and your friends are learning to play hockey, and you decide to use physics to get better by analyzing your movements. You are skating directly towards your friend at (5.98, 0) M/S who is also skating directly towards you to get the puck at a constant velocity of (-2.7, 0) M/S, and both of you reach the puck at the same time, so you collide and stick together. At the same time your hockey helmet with a mass of 5 kg goes flying away with a velocity of (0, 2.68) m/s. You have a mass of 74 Kg, your friend has a mass of 68 kg.
The questions:
1) In vector form, what is you and your friends velocity after you collide?
2) after the collision the puck is not moving on the ice and another player hits the puck towards the goal. If the average hockey player can apply a force of 80N over a 0.1s time and the goal is 15m away then provide evidence of whether or not the puck will reach the goal. the frictional force a puck experiences is 10N and the mass of a puck is .25kg. Consider friction in this case since the puck is made of a rough material.
Please show all work and explain why you are using the equations you are using !! Thank you so much. My physics teacher doesn't teach at all.

You are out playing
golf one day with your friends. And you decide to use your 60°
wedge to play a shot. The start of the green is right at 110 meters
away and the back is at 135 meters. Your club has a mass of .33 kg
and the golf ball has a mass of 40 grams or .04 kg. You swing the
golf club with a speed of 32 m/s.

You and your friends are doing physics experiments on a frozen
pond that serves as a frictionless, horizontal surface. Sam, with
mass 76.0 kg , is given a push and slides eastward. Abigail, with
mass 56.0 kg , is sent sliding northward. They collide, and after
the collision Sam is moving at 36.0 ∘ north of east with a speed of
6.20 m/s and Abigail is moving at 21.0 ∘ south of east with a speed
of 9.20 m/s ....

For lunch, you and your friends decide to stop at the nearest
deli and have a sandwich made fresh for you with 0.103 kg of
turkey. The slices of turkey are weighed on a plate of mass 0.430
kg and placed atop a vertical spring of negligible mass, with a
force constant of k = 170 N/m. The slices of turkey are dropped on
the plate all at the same time from a height of 0.310 m. They make
a...

You are your friends decide to start a milkshake shack in
downtown Newberg, Oregon at the local food cart pod. The name of
your new business is Udderly Delish. You decide to sell three
different kinds of milkshakes (whole milk, almond milk and coconut
milk) that are all the same size, 20 ounces. They will sell for $8,
$9 and $10 respectively. Customers can choose from a variety of 10
different flavorings (vanilla, chocolate, salted caramel, hazelnut,
strawberry, marionberry, blueberry,...

Your friends and you decide to purchase a large tract of forest
land in northern Minnesota with the intent of generating income
from timber and leasing the hunting rights. Your estimated costs
and returns are as follows:
• $1400/acre purchase price of land, paid back in equal yearly
installments over 15 years @ 7% annual interest.
• $200/acre site preparation costs incurred immediately.
• $250/acre tree planting costs incurred 1 year after
purchase.
• $100/acre forest management costs incurred 3,...

First, launch the video below. You will be asked to use your knowledge of physics to predict the outcome of an experiment. Then, close the video window and answer the question at right. You can watch the video again at any point. Suppose we repeat the experiment from the video, but this time we use a rocket three times as massive as the one in the video, and in place of water we use a fluid that is twice as massive...
