Answer:
a) t = 22.5 seconds
b)
c) in the same direction of the car.
Explanation:
First of all, let's convert the speed of the car to m/s:
Now, since the police officer catches the car, we know that their position is the same 750m, so:
Solving for t, we get:
t=22.5s Solved part a)
For the acceleration:
Replacing values and solving for a:
Solved part b)
For the velocity:
Solved part c)
Answer:
a)52.58 m/s
b)56.13°
Explanation:
assume the upward direction as positive
x-component of the velocity = 29.3×cos33.6°=24.40 m/s (remain constant)
y-component of the velocity which is -29.3sin33.6°= -16.21 m/s
time of flight = 68.3/24.40= 2.7991 seconds
now, we can obtain final velocity in y-direction
=43.66 m/s
=52.58 m/s
for direction
56.13° from the horizontal
I believe that the answer to the question provided above is that with increase in resistance provided with constant current, Power dissipated will be lessen since power loss is high. Low power dissipation has low heat production. Hope this helps!! Have a great day!! :)
