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
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.
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
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
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.
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.
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.
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.
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)
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.
1 min 40 sec or 100 sec.
5 m/sec More correctly: 5 m/sec2
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
