ing effects Q2 a situation when the position is irm that the action for the first effe placement, A nst , was +, 0, or - and

→ An ion's position vector is initially = 7.01 - 7.01 + 9.0k, and 5.0 s later it is = 5.01 + 6.0 - 5.0k, all in meters. What was its the 5.0 s? (Express your answer in vector form.) V avg Additional Materials m/s Algebra-Squareroots & Squares avg during

5) A disk of mass m = 75.0 g and radius r = 4.20 cm glides across an air table at a speed v = 1.5 m/s. It makes a glancing collision with a hoop of radius R = 5.80 cm and mass M = 130 g (initially at rest) such that their rims just touch. Because their rims are coated with instant-acting glue, the two objects stick together and rotate after the collision. a)  What is the angular momentum of the system relative to the center of mass? b)  What is the angular speed about the center of mass?

I do not need a quick answer, but I hope it is correct and in clear handwriting if you don't mind

PART A info card For vectors B -î – 4ĵ and A -32 – 21, calculate the following. Give your answers to three significant figures. PART B short answer The magnitude of B + Á number

Estimate the thickness of the Earth's atmosphere. From your chemistry class, you know that the most common speed of a nitrogen molecule is 700 m/s. The molecules' velocity is pointed along random directions, but some molecules head straight up; i.e. directly away from the Earth's center. Consider the thickness of the atmosphere as the highest point that such a nitrogen molecule can fly to, if it goes straight up. What is the altitude? m

physics, pleaassssse solve question 4

M Hello, i need help understanding how do you find the sin and cosine of E1 x and y along with E2 x and y. This problem is complete that im showing here please explain with this problem how you got the sin and cosine to start the problem for vector addition!!!
