Answer:
17 m/s south
Explanation:
= Mass of dog = 10 kg
= Mass of skateboard = 2 kg
v = Combined velocity = 2 m/s
= Velocity of dog = 1 m/s
= Velocity of skateboard
In this system the linear momentum is conserved
The velocity of the skateboard will be 17 m/s south as the north is taken as positive
Answer:
The y-component of the normal force is 45.74 N.
Explanation:
Given that,
Mass of the crate, m = 5 kg
Angle with hill, 
We need to find the y component of the normal force. We know that the y component of the normal force is given by :
So, the y-component of the normal force is 45.74 N. Hence, this is the required solution.
A radio wave is generated by a transmitter and then detected by a receiver. An antenna allows a radio transmitter to send energy into space and a receiver to pick up energy from space. Transmitters and receivers are typically designed to operate over a limited range of frequencies
For the answer to the question above,
<span>To be 0.1 miles away from the check point ,
the car has to travel 1.4 miles OR 1.6 miles. </span>
53 miles = 60 minutes
1.4 miles = 1.4 / 53 X 60 = 1.5849056 minutes OR 95.1 seconds
<span>1.6 miles = 1.6 /53 X 60 = 1.8113207 minutes OR 108.7 seconds
</span>So the answer is <span>95.1s and 108.7s
I hope my answer helped you</span>
All of the controls can cause acceleration. The gas pedal and brake cause the car to change speed and the steering wheel can cause a change in velocity by changing its direction which is also acceleration.
