Magnitude of gravitational acceleration on mercury?
Mercury's acceleration of gravity in m/s^2 is 3.59
Is acceleration a base unit?
No. It is derived from the fundamental SI units of length, the meter, and time, the second. The derived unit for acceleration is m/s/s or m/s2.
A cyclist is traveling at an initial speed of 10 ms She accelarates at a rate of .500 ms find her final speed after 9 s?
Her final speed is 14.5 m/s. The kinematics equation v = at + v0 will be useful here. Note that t is the time measured in seconds, a is the acceleration, v0 is the initial velocity, and v is the velocity after t seconds (the final velocity). We are given that v0 = 10 m/s, a = 0.500 m/s2, and t = 9 s. Using the above kinematics equation we get v = (0.500 m/s2)(9 s) + 10 m/s = 14.5 m/s. Since speed = |velocity|, then her final speed = |14.5 m/s| = 14.5 m/s.
If a net force of 120N gives an object an acceleration of 1.5 m s s what is the mass of the object?
Force is equal to the acceleration times mass. So, 120 N = 1.5 ((m/s)/s) times mass. So, the mass is 80 kg.
If aunt Minnie drops a penny into a wishing well and it falls for 3 seconds before hitting the water How fast is it going when it hits?
30 m/s The acceleration due to gravity is 9.81 m/s2. So, after the 1st second, it is traveling 9.81 m/s. After the 2nd second, it is traveling 19.62 m/s. After the 3rd second, it is traveling about 30 m/s.
What forces are difined as?
Acceleration is the change in velocity (m/s) divided by time (s), which is the same as meters divided by time in seconds squared (m/s2).
What is the base unit for acceleration?
m/s/s or m/s2
What is the dimensions of acceleration?
The equation for centripetal acceleration is a = v2/r, where a is acceleration, v is velocity in m/s, and r is the radius of the circle in meters. So the dimension of the acceleration a = (m/s)2/m = m2/s2/m, which gives m/s/s or m/s2. The direction of the acceleration is toward the center of the circle.
What is 9.8 m s2?
9.8 m/s 2
A sports car accelerating from rest was timed over 400m and was found to reach a speed of 120kmh in 18.0 secs C what was its average acceleration in m s2?
120kmh divided by 3,6 makes it 33.333 M/s and 33.333M/s divided by 18 seconds is 1.85M/s^2
What is the value of 9.8M per s' 2?
The acceleration due to gravity on the earth, known as g, is 9.8m/s2 or 9.8m/s/s, which means that a falling object falls with an increasing velocity of 9.8m/s every second, or 9.8m/s/s, which means 9.8 meters/second/second. m/s/s can be written as m/s2, because m/s/s means m/s ÷ s/1 = m/s x 1/s = m/s2.
How long does it take a truck to go from 5m per sec to 28 m per sec if its acceleration is 4.5m per sec squared?
Change in velocity: (28 m/s) - (5 m/s) = 23 m/s Change in velocity divided by acceleration: (23 m/s) / (4.5 m/s2) = 5.111 seconds.
Find acceleration from 0m per s to 5m per s in 4 seconds?
Acceleration = (change in speed) divided by (time interval).A = 5/4 = 1.25 m/s2
If a small lead ball falls from a high tower on Earth what will be its velocity after 2 seconds?
v = a X t. a = 9.8 m/s2 (acceleration) and t = time. At t = 2 seconds, v = (9.8 m/s2) X (2 s) = 19.8 m/s. At t = 4 seconds, v = (9.8 m/s2) X (4 s) = 39.6 m/s. [ANSWER: at t = 2 s, v = 19.8 m/s ; at t = 4 s, v = 39.6 m/s. ]
What is the cars acceleration if it accelerates uniformly from rest to 24 ms south in 18 s?
24 (m/s) / 18 s = 1.33 m/s/s or 1.33 m/s224 (m/s) / 18 s = 1.33 m/s/s or 1.33 m/s224 (m/s) / 18 s = 1.33 m/s/s or 1.33 m/s224 (m/s) / 18 s = 1.33 m/s/s or 1.33 m/s2
What do you measure acceleration in?
Metres per second squared (m/s^2 , m/s2 )
What will an object's speed be in 8 seconds in free fall?
(9.8 m/s2)(8 s) = 78.4 m/s
