Answer:
<h2>1.75 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 3.5 × 0.5 = 1.75
We have the final answer as
<h3>1.75 N</h3>

Answer:
3000W
Explanation:
Given parameter:
Weight of safe = 2000N
Height of lift = 6m
Time = 4s
Unknown:
Power used by Rudolph = ?
Solution:
Power is the rate at which work is being done. It is expressed as:
Power = 
Work done = Weight x height = 2000 x 6 = 12000J
Power = 
= 3000W
