A ball rolls 1m across a table after being uniformly accelerated down a small ramp. The results of 3 time trials are as follows: Trial Ad At 1 1m .39s 1m .41s 1m .35s Average If the ball was then allowed to roll off the table, at what speed (vx) would it be rolling? Use the constant velocity equation, v = Ad / At , to solve for v,. If the table is measured to be 82cm high, how far from the edge of the table will the ball land? Note: You will need to convert cm to m.

A ball is dropped from a window 50 m above the ground. a) How long does it take the ball to reach theground?b) What is its final velocity?2. A pebble was dropped from the window of a building, 80 meters above the ground. a) How many seconds willit take the pebble to reach the ground? b) How fast is it after 2.0 seconds? c) When will its velocity be 25 m/s?3. A stone is tossed upward at the moment a ball is dropped from a height of 25 meters. The stone’s initialvelocity is 25 m/s. At what height will the two meet? In how many seconds.4. A ball is thrown downward with an initial velocity of 20 ft/s. a) How fast is it moving 2s later? b) How fardoes it fall in these time ?

Please answer the following, thank you!

A stuffed giraffe is launched at a velocity of 35 m/s at a 30.5 degree angle. What is the maximum height reached by the stuffed giraffe? Aldrich is flving a drono and dror

What is her velocity at 15 s?

NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec.                                           Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.

olem 1. A stone is dropped from the top of a building and falls freely from rest. What is its position (height) and its velocity after 1.0s, 2.0s, and 3.0s? To find for the position (height), we will use: Know that initial velocity (vi) = 0 a. Find h after 1.0s h=0(1.0s)-(9.8 m/s)(1.0s)2 2 |h=v₁t - 9² 2 h=0-9.8m 2 h=-4.9 m (negative sign denotes downward direction) b. Find h after 2.0s h=0(2.0s) - (9.8 m/s²)(2.0s)² 2 h=0-39.2 m 2 h = -19.6 m or 19.6 m downward Given: v₁ = 20 m/s Find: a. v after 1s b. v after 5s c. d after 1s d. t from origin to maximum height d from origin to maximum height e. Solutions: a. y after is use: V₁ = v₁ - gt vy=20 m/s-(9.8 m/s²)(1.0s) vy= 20 m/s -9.8 m/s vy=10.2 m/s b. v after 2s use: Sample Problem 2. A boy threw a ball upward with an initial velocity of 20 m/s and was able to catch it before it reached the ground on its return. a. What was the ball's velocity after 1s? b. What was the ball's velocity after 2s? c. What was its displacement after 1s? d. How…
