0 to 60 mph= 60*0.447 m/s=26.8 m/s in 15 sec
maximum acceleration of car:
26.8/15=1.8 m/s^2
0 to 55 mph= 55*0.447 m/s=24.6 m/s within 268 meters
a=24.6^2/2*268=1.13
This acceleration is less than the maximum possible acceleration, so the car can reach 55 m/s in 268 meters.
The acceleration is expressed in meters per second square, which really means (meters / second) / second. Every second, the skydiver will be 10 meters per second faster than the previous second. Therefore, after 3 seconds, he will have a speed of 30 meters per second.
50 meters in 10 seconds is faster. you go 5 meters per second in 50 meters per second, and you go 6 meters a second in 5 seconds..
It is not possible to answer this question without the starting velocity.
4 meters/2 seconds = 2 meters/second.
395000 meters/9000 seconds is 43.889 meters/second
No
The plane's velocity at 10 seconds will be 150 meters per second or 335.54 mph
The acceleration is expressed in meters per second square, which really means (meters / second) / second. Every second, the skydiver will be 10 meters per second faster than the previous second. Therefore, after 3 seconds, he will have a speed of 30 meters per second.
That depends what data you are given. Close to the Earth's surface, such an object will accelerate at 9.8 meters/second2, so if it starts from rest, after "n" seconds, it will have a speed of "9.8n" meters/second.
You can't tell from the information given. All you know is that the average acceleration is (change in speed) divided by (time for the change) = (6/8) = 0.75 meters per second2. The force required depends on the mass of the object to be accelerated by the force.
F = m a = (1,000 x 10) = 10,000 newton
50 meters in 10 seconds is faster. you go 5 meters per second in 50 meters per second, and you go 6 meters a second in 5 seconds..
1/2a(3.4)^2+[3.4a(a=0)](6.6)=100 [] is Vi and a in this case is 0 at it stops to accelerate when it gets to 3.4s so a=100/(.5)(3.4)^2....=17.30 now Vf=(3.4*17.30)+17.30(6.6)...=173.01
It is not possible to answer this question without the starting velocity.
Divide total meters by total seconds to get meters per second
Her average acceleration is 2.2 meters per second per second (2.2 m/s2 ).
