Question
>>>this I believe is a two part question, one needs to be solved before the other I think.<<<
[Question 1]
Consider a projectile motion experiment in which a bullet (Ball) is fired from a spring-loaded gun from a height of 1.00 meters and it lands on a platform 30.0cm high. the range is measured to be 2.50 m. find the Muzzle speed of the bullet.
[Question 2]
Consider a projectile motion experiment in which a bullet (Ball) is fired from a spring-loaded gun from a height of 1.00 meters and it lands on a platform 30.0cm high. the range is measured to be 2.50 m. find the time of flight on the bullet.
A. 7.2 m/s B. 5.8 m/s C. 4.2 m/s D. 6.6 m/s E. 3.4 m/s F. none of themExplanation / Answer
The muzzle speed of the bullet is
u = R/ sqrt 2h/g
= 2.5 m/ sqrt 2 ( 1.0 m - 0.3 m)/ 9.8 m/s^2)
= 6.6 m/s
(2)
time of flight on the bullet is
t = sqrt 2h/g = sqrt 2 ( 1 m- 0.3 m)/ 9.8 m/s^2
=0.38 s
