A particle initially located at the origin has an acceleration of . Find the vector position of the particle at any time t (where t is measured in seconds). Find the velocity of the particle at any time t. Find the coordinates of the particle at t = 3.00 s. Find the speed of the particle at t = 3.00 s. A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 9.20 m/s at an angle of 21.0 degree below the horizontal. It strikes the ground 4.00 s later. How far horizontally from the base of the building does the ball strike the ground? Find the height from which the ball was thrown. How long does it take the ball to reach a point 10.0 m below the level of launching?

Explanation / Answer

Done...please rate me 5 stars!!!

s = v*t or 0.5 * a * t^2

v = a*t

SO we get the following results!!!

a) 8 ....2

b) 8... 4

c) x = 24

y = 18

d ) (8^2 + 12^2) ^ 0.5 = 14.42 m/s

2nd question :

a) 34.36 m

b) 91.67 m

c) 1.131 s
