3. Explain whether the following particular do or don not have acceleration: (a) a particle moving in a 4. Two projects are thrown with the same initial speed, one at an angle θ with respect to the level . Old book, problem 24, new book, problem 32. A fireman 50.0 m away from a burning building straight line with constant speed and (b) a particle moving around with constant speed. ground and the other an angle 90°-8. Both projectiles strike...
3. Two projectiles are launched simultaneously from the same location, with the same initial speed, one at 20° above horizontal, and the other at 32° above horizontal. The projectiles have different masses. Which one will strike the surface first? a. The one shot at 20°- angle. b. The one shot at 32°-angle. c. The heavier one. d. The lighter one. e. Both will strike it at the same time.
An object is thrown up at angle of θ=30º with the initial speed of 19m/s. i) Find the maximum height of the object and the maximum horizontal distance. ii) Find the minimum speed of the object during the motion. iii) Find the total time in the air.
Can anyone explains all the answers? Two balls, A and B are thrown at the same angle above horizontal, but initial velocity of ball A is two times greater than initial velocity of ball B. Ignore air resistance. we can conclude that horizontal range covered by ball A is same as range covered by ball B twice the range covered by ball B four times the range covered by ball B. greater than horizontal range covered by ball b, but...
1. A golf ball is hit with an initial velocity of 50.0 m/s at an angle of 34 degrees above the horizontal. If the golf ball lands on the same horizontal level, determine the time it takes the ball to stay in the air. 2. A ball is thrown horizontally, with a speed of 10 m/s, from the top of a 4.9 meter tall hill. How far from the point on the ground directly below the launch point does the...
A ball is thrown with an initial speed of 20 m/s at an angle of 60° to the ground. If air resistance is negligable, what is the ball’s speed at the instant it reaches its maximum height from the ground?
Three identical balls are thrown from the top of a building, all with the same initial speed. The first is thrown horizontally, the second at some angle above the horizontal, and the third at some angle below the horizontal. Neglecting air resistance, rank the speeds of the balls at the instant each hits the ground.
One strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching the first one, a second snowball is thrown at a low angle timed to arrive before or at the same time as the first one. Assume both snowballs are thrown with a speed of 10.0 m/s. The first one is thrown at an angle of 65.0° with respect to the horizontal. (a) At what angle should the...
One strategy in a snowball fight is to throw a snowball at a high angle over level ground. Then, while your opponent is watching that snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume both snowballs are thrown with a speed of 33.5 m/s. The first one is thrown at an angle of 66.0° with respect to the horizontal. (a) At what angle should the...
PRACTICE IT Use the worked example above to help you solve this problem. A ball is thrown upward from the top of a building at an angle of 30.00 to the horizontal and with an initial speed of 19.0 m/s. The point of release is h = 46.0 m above the ground. (a) How long does it take for the ball to hit the ground? 4.183 (b) Find the ball's speed at impact. 35.532 m/s (c) Find the horizontal range...
