What is the skydiver's downward velocity at that instant just before starting to fall?
The same as that of the aircraft that he /she is in. If flying level, it would be zero.
What is the angular velocity of the wheel before braking began if the wheel rotates through 6 radians in 2 seconds as it is uniformly brought to rest?
It was 6 radians per second. Angular acceleration = -3 radians per second2 Initial angular velocity = 6 radians per second. Final angular velocity = zero. Average angular velocity = 3 radians per second. Angular displacement in 2 seconds = 3 x 2 = 6 radians.
4 A car is traveling at a constant velocity with magnitude At the instant that the car passes a motor cycle officer the motor cycle accelerates from rest with acceleration a Sketch an grap?
# A car is traveling at a constant velocity with magnitude . At the instant that the car passes a motor cycle officer, the motor cycle accelerates from rest with acceleration . # ## Sketch an graph of the motion of both objects. Show that when the motor cycle overtakes the car, the motorcycle has a speed twice that of the car, no matter what the value of . ## Let be the distance the motorcycle travels before catching up with the car. In terms of , how far has the motorcycle traveled when its velocity equals the velocity of the car?
The velocity of a baseball 4 seconds after it is thrown vertically upward with a speed of 32.1 is?
If that's 32.1 meters per second initially, then after 4 seconds it's fallingwith a speed of 7.1 meters per second.If that's 32.1 feet per second initially, then it returns to the thrower's hand injust under 2 seconds, and it's in the dirt long before 4 seconds have passed.If it had been tossed at the edge of a cliff, then after 4 seconds, it would befalling with a speed of 96.7 feet per second.
Can You calculate the velocity of a fart?
Generally wind speed is measured using a cup anemometer (wind speed measuring device). The velocity of a flatulation will decrease as it leaves the anus, so to properly measure the velocity the measurement would have to be done before the exit. Theoretically you could measure the velocity of the gases by placing a miniature cup anemometer with walls inside the rectal tract close to the anus to give an approximate wind speed (velocity) of the gases.
What is the skydiver's downward velocity at that instant just before starting to fall?
The same as that of the aircraft that he /she is in. If flying level, it would be zero.
In projectile motion Why is the vertical component of velocity zero at the highest point of the trajectory?
Just before it reaches the highest point, the vertical component of velocity is upward.Just after it passes the highest point, the vertical component of velocity is downward.There's no way you can change from an upward velocity to a downward velocity smoothlywithout velocity being zero at some instant. A.True.
If you are 5 kilometers from the place where lightning strikes a tree how long does it take before you see the lightning?
.0000166782047599 seconds, or nearly instantaneously.
What is the momentum of a 500 kg truck before it strikes a 300 kg parked car?
Momentum defined as p=mv.. The momentum of the truck depends on its velocity
What makes a thrown upwards body to stop for some few seconds before desendeing down?
It DOES NOT stop for a 'few seconds' . It stop only for an instant as its movement changes from upwards to downwards.
An arrow is shot straight up at an initial velocity of 200 meters per seconds. How long will it be before beginning to fall?
40.81632653 or (rounded to the nearest 10th) 40.8 seconds
What is the duration of Before the Lightning Strikes?
The duration of Before the Lightning Strikes is 1.6 hours.
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity during this 5 second interval her acceleration?
the crate will reach terminal velocity last, but hit the ground frist.
When was Before the Lightning Strikes created?
Before the Lightning Strikes was created on 1959-10-04.
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity During this 5 second interval her acceleration will?
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
In physics is there a negative time?
Absolutely! If an object has been already traveling for 30 seconds. If you start your watch at 30 seconds, then t = 0 at 30 seconds! The velocity of the object 3 seconds BEFORE you start the watch would then be t = -3 and 3 seconds after you start the watch would be t = 3.
Is instant messaging allowed on dod systems?
Instant messaging allows two or more people to communicate in seconds. Some systems may allow these programs while others may not. It is best to check with the unit command and IT departments before downloading these programs.
