Answer:
67.9 kg*m/s
Explanation:
Pi = 38 kgm/s
F = 88.3N and ∆t = 0.338s
Final momentum Pf = Pi + F∆t = 38 + (88.3)(0.338) = 38 + 29.8454
=) Pf = 67.8454 kgm/s = 67.85kg*m/s
Your answer is 67.9kg*m/s with three significant figures
hope this helps your troubles!
Applications of Gas Law in Real Life. A torch used to heat up the and rise the air temperature inside the balloon. This cause the air volume inside the balloon to increased and becoming less dense than the surrounding air. ... The air in the ears will change its volume then causes yours ears to pop due to the strain.
Answer:
E) d_{2} = 4d_{_{1}}
Explanation:
We know that the range of a projectile is given by:
where:
u = initial velocity of the projectile
angle of projection of projectile
<u>Now, range for ball 1 :</u>
<u>Now, range for ball 2 with double velocity and all the other parameters being the same:</u>
