Answer:
Pressure = 5 x 10⁶ Pa
Explanation:
Given:
Height of building = 512 m
Find:
Pressure
Computation:
P2 = P1+dgh
P2 = 1 + (1000)(9.8)(512)
P2 = 51.2 atm
Pressure = 5 x 10⁶ Pa

Answer:

Explanation:
The acceleration of an object (or a person, as in this case) is given by

where
v is the final velocity
u is the initial velocity
t is the time interval
In this problem,
u = 20 m/s
v = 40 m/s
t = 10 s
Therefore Jill's acceleration is

Answer:
3000 N
Explanation:
We have,
• Mass, m = 1000 kg
• Acceleration, a = 3 m/s²
We have to find force required, F.
F = ma
F = 1000 × 3 N
F = 3000 N (Answer)
