Answer:
A) a = 7.89 m/s²
B) a = 3.51 m/s²
C) 4.38 m/s²
D) Frictional force
E) F_f = 5552.83 N
Explanation:
A) Formula for Force is;
F = ma
Where;
m is mass
a is acceleration
We are given;
F = 10,000 N
m = 1267 kg
Thus;
10000 = 1267a
a = 10000/1267
a = 7.89 m/s²
B) We are told the car covers 394.6 m in 15 seconds.
Using Newton's third equation equation of motion, we can find the actual acceleration.
s = ut + ½at²
u is zero since the object began from rest.
Thus;
S = ½at²
394.6 = ½ × a × 15²
a = 394.6 × 2/225
a = 3.51 m/s²
C) difference in accelerations = 7.89 - 3.51 = 4.38 m/s²
D) The force that caused the difference in acceleration is frictional force
E) To find the magnitude of the force that caused the difference in acceleration, we will use the formula;
F - F_f = ma
F_f = F - ma
Where F_f is the frictional force
Thus;
F_f = 10000 - 1267(3.51)
F_f = 5552.83 N
Answer:
Explanation:
velocity of ship with respect to water = 6.5 m/s due north
velocity of water with respect to earth = 1.5 m/s at 40° north of east
velocity of ship with respect to water = velocity of ship with respect to earth - velocity of water with respect to earth
The magnitude of the velocity of ship relative to earth is 
= 5.66 m/s
