In one contest at the county fair, a spring-loaded plunger launches a ball at a speed of 3.2m/s from one corner of a smooth, fla t board that is tilted up at a 20 degree angle. To win, you must make the ball hit a small target at the adjacent corner, 2.40m away. At what angle theta should you tilt the ball launcher?
1 answer:
Answer:
Explanation:
Given
Speed of ball
Plane is inclined at an angle
To win the Game we need to hit the target at away
Launch angle of ball
Motion of ball can be considered in two planes i.e. Vertical to the plane and horizontal to the plane
So Net acceleration in vertical plane is
Range of Projectile is given by
for
so ball must be launched at an angle of

#1). Anthony does the same amount of work as Angel, with <em>more power </em>.
#2). Power = (Work)/(Time) = 41,000 J / 500 s = <em>82 watts . </em>
#3). Power = (Work) / (Time) = 83 J / 3 sec = <em>27.7 watts </em>
Answer:
the question is wrong
Explanation:
M is not given after 9 second the acceleration multiply by the time divided by two then multiplied by the time is equal to 4 meter ((10/Mm/s *9s-)
