Problem 2: I throw a ball, mass m-5.0kg, at an initial speed of 3.0m/s, at an initial height of 1.7m, but at ar angle of 37" with respect to the horizontal. It lands on the ground, at a final height of zero. (a) What is the initial velocity? (This is a VECTOR. Define ti as the horizontal, and +j as the vertical.) (b) What is the time when the ball obtains its maximum height? (c) What is the maximum height...
0 - Incomplete Projectile Motion: Look again at chapter 3, sections 7 and 8. Problem 1: Problem 3.29 of Giancoli lan bah Problem 2: I throw a ball, mass m-5.0kg, at an initial speed of 3.0m/s, at an initial height of 1.7m, but at an angle of 37' with respect to the horizontal. It lands on the ground, at a final height of zero. (a) What is the initial velocity? (This is a VECTOR. Define ti as the horizontal, and...
QUESTION 1 A ball of mass 5.0kg is lifted off the floor a distance of 1.7m. 1. What is the change in the gravitational potential energy of the ball? 2. Now you release the ball from rest, and it falls to the floor. What is the kinetic energy of the ball just before it hits the floor? 3. What is the velocity of ball just before it hits the floor? QUESTION 2 Suppose that the ball in the last question...
From the top of a building, you throw a ball upward with initial velocity of 4.00 m/s at an angle of 50 degrees with respect to the horizontal. a) what are the velocity components of the ball at point A, B, C, and D? b) how far from the building is point D? From the top of a building, you throw a ball upwards with initial velocity of 4.00 m/s at an angle of 50° with respect to the horizontal....
Problem 2. (25 points) A golfer hits a golf ball with an initial speed of 30 m/s at an angle of 35° with the ground. The ball flies over the level ground and lands at the same height from which it was hit. a) How long does it take for the ball to reach its highest point? b) What is the range of the ball? c) Find the velocity of the ball just before it hits the ground. d) After...
Two throw A blue ball is thrown upward with an initial speed of 22.2 m/s, from a height of 0.8 meters above the ground. 2.7 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 9.2 m/s from a height of 27.8 meters above the ground. The force of grandly due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. What is the speed of...
From the top of a 70 m building, you throw a ball straight up at 6 m/s. The ball misses the building on the way down. What is the maximum height of the ball? What is the velocity of the ball after 2 s? What is the final velocity of the ball (just before it hits the ground) Now, the ball is thrown straight down at 6 m/s. What is the velocity of the ball after 2 s? Using the initial...
You throw a ball straight up. The ball has an initial speed of 11.2 m/s when it leaves your hand. A) What is the maximum height the ball reaches relative to the throwing point. B) How long does it take the ball to reach this height? C) What is the position of the ball at t=2s? D) At what height does the ball have a speed of +5m/s?
A ball is launched from the top of a building 80 m high at an angle of above the horizontal with a speed of 63 in/s. How long does it take before the ball reaches its highest point? What is the maximum height of the ball above the ground? How long is the ball in the air before it hits the ground? How far does the ball travel horizontally before it hits the ground? What is the acceleration of the...
A soccer ball is kicked with an initial horizontal velocity of 18 m/s and an initial vertical velocity of 13 m/s. 1) What is the initial speed of the ball? 2) What is the initial angle ? of the ball with respect to the ground? 3) What is the maximum height the ball goes above the ground? 4) How far from where it was kicked will the ball land? 5) What is the speed of the ball 0.8 seconds after...
