If an object goes from 60 mph to 10 mph in 5 seconds what is its acceleration?
-10 mph/sec
If an object goes from 50 mph to 30 mph in 5 seconds what is its acceleration?
-4 mph/sec (Study Island Answer)
How long does it take to reach a speed of 74 mph?
It all depends upon the acceleration. A fast car can probably do it in under 10 seconds. Driving economically would take much longer. A jet plane can do it quicker.
How long would it take a car to accelerate from 20 mph to 45 mph if its acceleration is 10 mphsec?
a = (vf - v0)/Δt 10 mph/s = (45 mph - 20 mph)/Δt Δt = 2.5 s
How fast would you have to drive to go 1 mile in 22.8 seconds?
About 163 mph
How long would it take a car to accelerate from 10 MPH to 75 MPH if its acceleration is 20 MPHs?
Acceleration = Change in speed/Time Time = Change in Speed/Acceleration = 65mph/20mph per s = 65/20 seconds = 3.25 seconds
If an object goes from 60 mph to 10 mph in 5 seconds what is its acceleration?
-10 mph/sec
If an object goes from 50 mph to 30 mph in 5 seconds what is its acceleration?
-4 mph/sec (Study Island Answer)
A motorcycle accelerates from 0 mph to 60 mph north in 3 seconds what is the acceleration of the motorcycle?
20 mph/s North
How fast would you be going if you went 800 feet in 10 seconds?
If you went 800 feet in 10 seconds, you would be going 800/10 = 80 feet per second, 237,600 mph.
How long would it take a car to accelerate from 15 MPH to 75 MPH if its acceleration is 20 MPH?
The formula for finding time based on acceleration and speed is: (Delta)t = (Delta)v/a Change in time = change in speed / acceleration t = 75-15 / 20 t = 60 / 20 t = 3 seconds
What is mikes acceleration in miles per hour per second if he can go from 0 to 40 in 5 seconds?
40 mph/5 sec = 8 mph per second. That happens to be within a few percent of the gravitational acceleration on the surface of Mars. In other words, if you dropped Mike onto Mars from a small distance above the surface, his descent rate would go from zero to 40 mph in about 5 seconds. Whereas, in the same 5 seconds spent falling to Earth, his descent rate would go from zero to almost 110 mph.
A motorcycle can accelerate from 0 to 60 in 3 seconds what is its acceleration in miles per hour per second?
To calculate acceleration in miles per hour per second, first convert the acceleration from 0 to 60 mph in 3 seconds to miles per hour. 60 mph / 3 sec = 20 mph/sec. So, the acceleration in miles per hour per second is 20 mph/sec.
How long would it take a car to accelerate from 10 mph to 45 mph if it's acceleration is 20 mph?
There is no such thing as 20 mph acceleration. 20 mph is a velocity. Acceleration is expressed as velocity per unit time e.g. mph per second or mph per minute etc.
If a roller coaster goes from zero to 80 miles per hour in 1.8 seconds what is its acceleration in miles per hour per second to the nearest tenth?
It goes from 0 mph to 80 mph in 1.8 seconds Acceleration = change in speed/time taken = (80 - 0)/1.8 mph per second = 44.4 mph per sec
What is a roller coasters average acceleration if its speed is 4 m s and three seconds later its 22 m s?
The acceleration of the roller coaster would be 88 MPH. This was figured out by doing math.
Mikes car can accelerate from 0 mph to 40 mph in 5 seconds. what is the acceleration of his car in miles per hour per second?
8
