the 4 fundamental kinematic equations of motion for constant acceleration (suggest you commit these to memory):
s = ut + ½at^2 …. (1)
v^2 = u^2 + 2as …. (2)
v = u + at …. (3)
s = (u + v)t/2 …. (4)
where s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.
In this case, we know u = 10m/s, v = 50m/s, t = 10s and we want to find a, so we use equation (3)
v = u + at
50 = 10 + 10t, so t = (50 – 10)/10 = 4m/s^2

What is the acceleration of car that increase its speed by 10 milessec after 30 seconds if the initial velocity was 20 milessec?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 20+10 = 30 miles/sec, the initial velocity is 20 miles/sec, and the time is 30 seconds. So, the acceleration of the car is (30 - 20) / 30 = 0.33 miles/sec^2.
How much force is needed to bring a 3500pound car from rest to a velocity of 48feet per second in to seconds?
Force = Mass x Acceleration Initial speed of car = 0, Final speed = 40 feet/sec in time 2 seconds Acceleration = (v-u)/t = (40 - 0)/2 = 20 feet/sec/sec Force = 3500 x 20 = 70000 pounds/sec/sec
What is a cars acceleration if it increases its speed from 5 m s to 20 m s in 3 s?
The answer will be 5 m/sec/sec 300m/sec - 200m/sec divided by 20 seconds will get you 100m/sec divided by 20 seconds, which then equals 5
If a car is approaching a stop light and slows from 20 meters per second to a stop in 5 seconds what is the acceleration?
The acceleration of the car can be found using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 0 m/s (stopped), the initial velocity is 20 m/s, and the time is 5 seconds. So, the acceleration would be (0 m/s - 20 m/s) / 5 s = -4 m/s^2.
What is the acceleration between 20 sec and 30 sec?
Well, isn't that just a happy little question! To find the acceleration between 20 seconds and 30 seconds, you would need to calculate the change in velocity during that time interval and divide it by the time taken. Remember, acceleration is how quickly an object's velocity is changing over time. Just like adding a touch of bright color to a painting, understanding acceleration can add a beautiful depth to your knowledge of motion.
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.
Calculate a car goes from 20ms to 30ms in 10 seconds. what is its acceleration?
The car's acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Plugging in the values, we get: (30 m/s - 20 m/s) / 10 sec = 1 m/s^2. The car's acceleration is 1 meter per second squared.
If your speed was 30 miles an hour and you sped up 50 miles and hour in 20 seconds. What was your acceleration?
Acceleration = (change in speed) / (time interval)= (50 - 30) mph / 20 sec = (20 mi/hr) (1/3,600 hr/sec) (5,280 ft/mi) / (20 sec)= (20 x 5,280) / (3,600 x 20) (mi - hr - ft / hr - sec - mi - sec)= 1.4667 ft/sec2 (rounded, repeating)
How long would it take a car to accelerate from 20 mph to 60 mph if its acceleration is 10 mphsec?
About .0011111 hours, or about 4 seconds.This is assuming the units are miles/(hour*sec), which converts to 36000 miles/(hour^2) as the acceleration.
What is the difference between 20 sec and 2 min?
1 min 40 sec or 100 sec.
What is the acceleration of an object that takes 20 seconds to change from a speedof 200 m per sec to 300 m per sec?
5 m/sec More correctly: 5 m/sec2
A car starts from rest and travels a distance of 100 m in 20 seconds with a constant acceleration The velocity of the car is at the end of the 20 second interval is?
velocity=5 meters/sec Velocity=change in distance/change in time velocity=m/s change in distance=meters change in time=sec v=x/t v=100m/20s v=5m/s
