Explanation:
Answer:
8 cm
Ladder is safer than to walk on it
Explanation:
Streched = Final length - initial length
= 66 - 58
= 8 cm
When your are walking along frozen ice pond your weight is not distributed .It's acting on directly on the ice pond because of contact Area is too small between pond and you. There for According to pressure equation ,
P = F/A
When area is less pressure is less.
If use ladder instead of going by foot. Contact area will be high between pond and ladder. There for pressure is reduced .
Time before projectile hits wall
= 88.2 m / 29.4 m/s = 3 seconds
Vertical velocity of projectile after three seconds
= 3*9.8 = 29.4 m/s
Horizontal velocity of projectile after three seconds, assuming no air resistance
= 29.4 m/s (given)
Conclusion:
velocity of projectile when it hits the wall
= < 29.4, -29.4> m/s
= sqrt(29.4^2+29.4^2) m/s east-bound at 45 degrees below horizontal
= 41.58 m/s east-bound at 45 degrees below horizontal.
