Answer:
Explanation:
Given
mass of climber= 62 kg
velocity of climber before it hits=7.9 m/s at an angle of
from vertical
therefore change in momentum in vertical direction is



there is no change in horizontal momentum
and impulse=change in momentum
F.dt=946.22

For non padded floor

Kinetic energy =(1/2) (mass) (speed²)
First object: KE = (1/2) (2 kg) (2m/s)² = 4 joules during the lift.
Second object: KE = (1/2) (4kg) (3 m/s)² = 18 joules during the lift.
The second object has more kinetic energy while it's being lifted
than the first object has while it's being lifted. Once they reach their
final heights and stop, neither object has any kinetic energy.
Answer:
maybe the rear wheel axel rusted not sure
Answer:
d = 90 ft
Explanation:
As we know that after each bounce it reaches to 4/5 times of initial height
so we can say

so the distance covered is given as

here we know that
h = 10 feet
