14.715 m/s.
This is worked out by knowing that gravity will accelerate a body at 9.81 (m/s)/s. The average velocity is the speed at 3s plus the speed at 0s divided by 2.
Speed at 0s = 0 x 9.81 = 0 m/s
Speed at 3s = 3 x 9.81 = 29.43 m/s
(29.43 + 0) / 2 = 14.715 m/s.

What is a skydivers average velocity for the first 3 seconds?
The average velocity for the first 3 seconds of a skydiver's free fall would depend on the initial speed, air resistance, and gravitational acceleration, but generally, it could be around 55-60 m/s.
Is it possible for the average velocity of an object to be zero during some interval even thought its average velocity for the first half of the interval is not zero explain and cite an example?
Yes, it is possible for the average velocity of an object to be zero during some interval, even if its average velocity for the first half of the interval is not zero. This can occur if the object moves in opposite directions with equal distances during the two halves of the interval. For example, if a car moves 3 miles east in the first half of an hour and then moves 3 miles west in the second half of an hour, its average velocity for the entire hour would be zero.
You drop a ball from a cliff it lands 4 seconds later what is the balls average speed during the 1st second it is in free fall?
The basic equation for average velocity is distance over time. However, if the velocity is changing uniformly, as it is in free fall, you can use initial velocity plus final velocity divided by two. That makes this problem easy. In free fall the object accelerates at 9.8 m/ss. That means every second it picks up 9.8 m/s of speed. So if is dropped from rest, then one second later its speed will be 9.8 m/s. Its average speed during that time is then initial velocity = 0 plus final velocity = 9.8 divided by 2, to get ; 4.9 m/s.
The body travels 2mts in first 2 seconds and 2.2mts in next four seconds what will be the velocity at the seventh second?
heres the average 2.2 seconds
Is there a difference between meters per second and meters?
Yes. The first is a speed (or velocity), the second is a distance.
What is its average acceleration over the first 5.1s of its motion?
To find the average acceleration over the first 5.1 seconds of motion, divide the change in velocity over that time period by the time taken. Calculate the final velocity minus the initial velocity over 5.1 seconds to find the average acceleration.
Skydivers spend the first several seconds of their jump in freefall?
TrUe <3 (=
How are position, velocity, and acceleration related?
Position, velocity, and acceleration are related in that velocity is the rate of change of position, and acceleration is the rate of change of velocity. In other words, acceleration is the second derivative of position, and velocity is the first derivative of position.
True or false Skydivers spend the first several seconds of their jump in free fall?
True. Every second of a jump is in freefall from when the jumper leaves the plane until the deployment sequence begins.
The maximum velocity of a ball as it drops is 12 meters per second. The maximum velocity of the ball after the first bounce is -6 meters per second. What is the difference between the two velocities?
18
What is the distance that the object travels in the first 5 seconds?
To find the distance traveled in the first 5 seconds, we multiply the average velocity by the time traveled. If the object's velocity is constant, this distance is equal to the velocity multiplied by the time.
My first semester comulative average is 85 how do they calculate the average of second semester?
The second semester cumulative average will be calculated by the number of units in your second semester.
