Explanation:
Answer:
the work done on the car by the applied force is 75 J.
Explanation:
Given;
initial velocity of the car, v = 4 m/s
applied force in opposite direction, F = 5N
initial position of the car, x₀ = 5 m
final position of the car, x₁ = 20 m
displacement of the car, Δx = x₁ - x₀ = 20 m - 5m
= 15 m
The work done on the car by the applied force is calculated as follows;
W = F.Δx
W = 5 x 15
W = 75 J
Therefore, the work done on the car by the applied force is 75 J.
B. 5/9 degree Fahrenheit.
C. one kelvin.
D. 9/5 kelvin.
Answer:
t = 10.4 s
Explanation:
given,
velocity of the police car = 18 m/s
reaction time of policeman = 0.8 s
acceleration of the policeman to catch up the speeder = 5 m/s²
time taken to catch the speeder be t₁
distance traveled by the police and the speeder will be same
t₁ = 9.6 s
total time taken by the policeman
= reaction time + t₁
= 0.8 + 9.6
t = 10.4 s
Total time taken by the policeman to catch the speeder is 10.4 s
