Answer:
<em>110.7Joules</em>
Explanation:
<em>Work is said to be done when the force applied to a body cause the body to move through a distance.</em> Mathematically:
Work done = Force * Distance
Given the following
Force = 270 -0 = 270N
Distance moved = 0.410m
Required
The work done
Substitute the given parameters into the formula
Workdone = 270 * 0.41
Workdone = 110.7Joules
<em>Hence the work done in pulling the bow is 110.7Joules</em>
D. 289
Take the formula:
K=5/9(Fahrenheit-32)+273
Plug in Fahrenheit
K=5/9 (60-32)+273
From here it is simple math and you can plug it into your calculator getting 288.5555556 and round to 289
Acceleration = ▵v/▵t
Time = d/v
Fisrt calculate time : ( 118/29 ) = 4 seconds
Then calculate acceleration
A = 29/4 = 7.25 m/s²
Now the force.
Force = mass * acceleration.
F= 1,019 * 7.25
F= 7,387 N
Answer:
speed and direction
Explanation:
Acceleration is the rate of change of speed and direction.
