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…

A ball is dropped from a height of 6m above the ground. The velocity of the ball when reaching the ground is O a. 7.66 m/s O b. 10.84 m/s O c. -9.8 m/s Od. 10,84 m/s

A car starts from rest and foes down a slope with constant acceleration of 5m/s2. After 5s, the car reaches the bottom of the hill. What is the car's speed at the bottom of the hill (in meters per second)? O 160 O 50 О 12.5 O 25 O 1

5. A boy throws a rock into a 10.0 m deep well at 4.00 m/s [down]. a) What is the velocity of the rock when it hits the bottom of the well? b) How long will it take to hit the bottom of the well? Inal disdac
