Answer:
<em>The crane lifts the crate up to 76 m high</em>
Explanation:
<u>Work Done by a Force</u>
The work done by a force of magnitude F that displaces an object by a distance y is given by
We know a crane does a work of 9,500 Joule to lift a crate and is using a force of 125 Nw.
The above equation can be solved to know the value of y in terms of the work and the force:
Plugging in the given values
The crane lifts the crate up to 76 m high
Answer:
"The weight of an empty bottle is 10N...Calculate the mass of the empty bottle."
w=Weight; m=Mass; g=Gravity
w=mg
w/g=m
10/9.81=m
1.019368kg = m

Answer:
180 meters
Explanation:
We know initial position and velocity of the dragster are both zero. We only know acceleration (43 m/s^2) and need to find out how far the dragster moves after 2.9 seconds.
x initial = 0
velocity initial = 0
t=2.9s
a= 43m/s^2
Plug into
180 meters or 1.8 x 10^2 meters is the answer accounting for 2 sig figs.
