THE BALL'S ACCELERATION IS 130.90
Explanation:
According to Newton's second law "the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a)", meaning that when the soccer player kicks a ball, a force is acting on the ball, therefore increasing it's acceleration
SO FOR CALCULATING THIS WE WILL USE NEWTON LAW,
FORCE = MASS × ACCELERATION
WE ARE GIVEN
FORCE = 57.6N
MASS= .44KG
SO HERE WE APPLYING FORMULA ,WE WILL GET
ACCELERATION =
ACCELERATION =
ACCELERATION =130.90
Answer:
Explanation:
a. Internal energy and the relative specific volume at are determined from A-17:
.
The relative specific volume at is calculated from the compression ratio:
#from this, the temperature and enthalpy at state 2, can be determined using interpolations
and
. The specific volume at
can then be determined as:
Specific volume,:
The pressures at is:
.The thermal efficiency=> maximum temperature at can be obtained from the expansion work at constant pressure during
b.Relative SV and enthalpy at are obtained for the given temperature with interpolation with data from A-17 :
Relative SV at is
=
Thermal efficiency occurs when the heat loss is equal to the internal energy decrease and heat gain equal to enthalpy increase;
Hence, the thermal efficiency is 0.563
c. The mean relative pressure is calculated from its standard definition:
Hence, the mean effective relative pressure is 674.95kPa
Answer:4.34 miles
Explanation:
first Elevation =
After 1 minute Elevation changes to
Ditsance travelled in 1 minute ==10 mile
Now
tan59=
H=xtan59
tan19=
H=
Equating H
we get
1.319x=10tan19
x=2.61 miles
H==4.34 miles
