Answer:
It makes it more difficult to move, making it stretch and exercise your muscles better becuse there is a resistant force to overcome.

Enclosed is some guidance algebra.I find this q a little confusing. It quotes "RC" which usually makes me think of electrical circuits and time constants based on converting calculating RC value and equating that to t for one time constant then 2RC for two time constants etc. The theory being that after 5 time constants - 5RC - a circuit is stable. BUT, this q then goes on to mention HALF LIFE. The curves for both half life and time constant are both exponential, as in the number e to the power of something, but the algebra is slightly different. I hope my algebra is ok.
Answer:
Flight path angle= 15.12°, maximum range= 5.29× 10*6 km
Explanation:
u= 7200m/s, H= 180km= 180000m
Recall that
Maximum height, H= (u*2sin*2∆)/2g
180000= (7200×7200sin*2∆)/2×9.8
(18000×2×98)/7200×7200= sin*2∆
Sin∆= 0.2609
∆= 15.12°
Maximum range, R= u*2/g
(7200×7200)/9.8
= 5289795.92km
= 5.29× 10*6 km

Answer:
Conservation of momentum - causes a recoil of cannon frame after launch
Explanation:
- It is simple, we can apply the conservation of momentum on the system. Initial momentum P_i before shooting is zero. Then after you strike the cannon up, the ball will go to the target however for the momentum to be conserved the cannon frame must move backwards with the same momentum with which the cannon ball is launched.
Hence, the recoil of the cannon frame would be large enough to dislodge you off the ground and throw you a few feet back.
