A sports car is advertised to be able to stop in a distance of 50 m from a speed of 90 What is its acceleration in m-s 2 how many G's is this?

d=50m Vi=90km/h(25 m/s) Vf=0
changing km/h to m/s--> 90x1000/3600= 25
Use: Vf^2= Vi^2+2ad
0^2= 25^2+ 2a50
= -81 m/s^2

What is acceleration speed and velocity?
Speed is (distance covered) divided by (time taken to cover the distance).Velocity is a speed and its direction.Acceleration is any change of velocity.
Compare and contrast speed and acceleration?
-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.
How do distance-time and speed-time graphs help explain an object's motion?
Distance - Time shows speed (by gradient) and distance travelled over a given time. Speed - time shows acceleration and instant speed.
How is average velocity different from acceleration?
For a start, acceleration doesn't even have the same units as velocity: acceleration is a velocity divided by time, so while speed or velocity have units of [distance]/[time], acceleration has units of [distance]/[time squared]
What distinguishes the measurement of speed from that of velocity and acceleration?
SPEED only considers a magnitude, not the direction in which something is moving.VELOCITY does consider the direction. ACCELERATION is the rate of change of speed, so it has units of speed/time, or distance/time squared.
What are the importance of speed velocity and acceleration in sports?
what are important speed, velocity and acceleration in several sports
How do you find distance given acceleration and speed?
acceleration times speed
What is the equation for average speed and acceleration?
Average speed = Distance travelled/time to travel the distance . Average acceleration = Change of speed/time for the change .
What are two equations for speed?
Speed = (distance covered) divided by (time to cover the distance) Speed = (magnitude of acceleration) multiplied by (time the acceleration has acted)
How are acceleration and speed alike?
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.
Math in sports?
Speed= distance/time Distance= speed x time Time= distance/speed
What is the definition of math in sports?
Speed= distance/time Distance= speed x timeTime= distance/speed.
Is acceleration the change of distance over time?
No, acceleration is the change in speed over time.
What is the formula for speed and acceleration?
formula for speed is distance traveled over time taken to cover distance acceleration is given by change in velocity per unit time
What is acceleration speed and velocity?
Speed is (distance covered) divided by (time taken to cover the distance).Velocity is a speed and its direction.Acceleration is any change of velocity.
Is acceleration the slope of a line on a distance time graph?
No. The slope of the distance-time graph is the change in distance per unit of time - otherwise known as speed. Acceleration is the slope of the speed time graph.
What is the formula for distance traveled in acceleration?
If starting from rest, Distance = 1/2 (acceleration) x (time)2 . Otherwise, Distance = 1/2 (initial speed + final speed) x (time)
