If we neglect friction/air resistance, then the horizontal component
doesn't change, and the vertical component becomes (9.8 m/s downward)
greater each second thanks to gravity.
So, after 2 seconds, the horizontal component is still 40 m/s, and the
vertical component is (30 - 2·9.8) = 10.4 m/s upward.
Choice #1 says this.
Answer:
a. A uniform disk of radius and mass .
Explanation:
The moment of inertia I of an object depends on a chosen axis and the mass of the object. Given the axis through the point, the inertia will be drawn from the uniform disc having a radius and the mass.

Why are the types of shoes you wear in the kitchen important?
• One of the best ways to prevent slip and fall accidents at work is to wear the right type of shoes. Footwear is paramount when it comes to safety in a kitchen setting. Grease spilled liquids, and vegetable debris can litter a chef's floor at any time, presenting major slip and fall hazards.
What are the possible consequences of wearing inappropriate footwear in the kitchen?
• Non-slip shoes greatly reduce the risk of accidents in the kitchen. Slips and falls can result in bruises, bleeding, broken bones, and concussions. If someone falls in the wrong place, he or she could receive serious burns or knife wounds.
Answer:
Cart B has a smaller mass
Explanation:
I may be wrong but if mass is decreased then acceleration increases, and if velocity increases then acceleration increases so my logic is that if mass decreases then velocity increases.
Answer:
90J
Explanation:
The only time work is being done is when he lifts the box off the ground. Therefore, using the work formula, 2 x 45, you get 90J. Hope this helps someone.
