A skydiver slows down from 65 m s to 5 m s by opening the parachute If this takes 0.75 seconds what is the skydiver's acceleration?
The general formula for acceleration is [(final velocity) - (initial velocity)]/(time required for the change). In this instance, (5 - 65)/0.75 = -80 meters per second per second.
How do you find average acceleration?
Acceleration = (change in speed) divided by (time for the change)
How do you calculate time with speed and acceleration?
Average acceleration = Change in speed/time so Time = Change in speed/Average acceleration
What is the Formula for calculating net acceleration?
Net acceleration = (change in velocity) divided by (time for the change)
How do you find acceleration using velocity and time?
Acceleration = (change in velocity) divided by (time for the change)

A skydiver slows down from 54 ms to 5 ms by opening his parachute. If this takes .75 seconds what is the magnitude of the skydiver's acceleration?
The change in velocity is 54 m/s - 5 m/s = 49 m/s. The time is 0.75 seconds. Using the equation a = (vf - vi) / t, the acceleration is (49 m/s) / (0.75 s) = 65.33 m/s^2.
Does it mean a skydiver is slowing down if the acceleration of the skydiver decreases as falling progresses?
Yes, if the acceleration of the skydiver decreases as falling progresses, it means the skydiver is slowing down. This indicates that the force of gravity pulling the skydiver downward is being countered by air resistance, causing the skydiver to decelerate.
A skydiver slows down in 54 ms to 4 ms by opening his parachute if it takes 0.75 What is is the magnitude of the skydivers acceleration?
To find the acceleration, we first calculate the change in velocity: 4 m/s - 54 m/s = -50 m/s. Next, we use the formula for acceleration: acceleration = change in velocity / time = -50 m/s / 0.75 s = -66.67 m/s^2. The magnitude of the acceleration is 66.67 m/s^2.
A skydiver slows down from 65 ms by opening the parachute if this takes 0.75 seconds what is the skydivers acceration?
To calculate this, you divide the change in velocity, by the time.

66.7 m/s2
what force is increased after the skydiver open parachute?
To start with there is gravitational attraction. As soon as the skydiver starts falling, (s)he will experience the drag force due to air resistance. The gravitational force is essentially constant but the drag increases as the diver's velocity increases until it equals gravity. The diver is the falling at terminal velocity and will continue to do so until the parachute is operated.
How can you increase or decrease acceleration?
To increase acceleration, you can apply more force or reduce resistance. This can be achieved by pushing harder on the gas pedal in a car or reducing air resistance by changing body position while skiing. To decrease acceleration, you can apply less force or increase resistance, such as by letting off the gas pedal in a car or increasing air resistance by opening a parachute while skydiving.
What is the skydiver's downward velocity after 1 second?
The skydiver's downward velocity after 1 second can vary, but on average it is around 9.8 m/s, the acceleration due to gravity. This value can change based on various factors such as air resistance, body position, and altitude.
What will be the effect of the acceleration due to gravity while jumping with a parachute?
The acceleration due to gravity doesn't change near the earth's surface, no matter what the cause of your fall is, or what position you assume during the fall, or what you're wearing. But a parachute sets up significant force opposite to gravity, because of air resistance. Since the acceleration is proportional to the net force, it can be reduced when there is considerable force canceling a significant fraction of the gravitational force.
How does a skydiver change his or her speed?
Just as a leaf falls slower to the ground than a tennis ball, a skydiver changes his/ her body position to change the amount of surface area that is affected by air resistance. A flatter body position, for example, will slow a skydiver's freefall rate from a normal arched position.
Is there an acceleration when an object traveling at constant velocity and why?
No, there is no acceleration when an object is traveling at a constant velocity. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change and therefore no acceleration.
