There are 60 seconds in a minute, so 12 minutes would have 12 x 60 = 720 seconds. Adding half a minute, which is 30 seconds, to this total gives us a final count of 720 + 30 = 750 seconds in 12 and a half minutes.
Forty seconds is two thirds of one minute.
Do your own homework! The train travelling at the constant speed will still be doing 16ms after 10 seconds The other train adds 1m per second so, after 10 seconds it will have added 10, 10 + 8 = 18ms. It is going faster. or : you can find the final velocity : final velocity = vi+a(t) = 8+1(10) =18 m/s So Train B is faster.
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
30mph
The final velocity can be calculated using the equation: final velocity = initial velocity + (acceleration x time). Plugging in the values, we get final velocity = 45 mph + (-10 mph/sec x 3 sec) = 45 mph - 30 mph = 15 mph. Therefore, the final velocity of the object is 15 mph.
Typically, the countdown for a space shuttle launch starts at T-43 hours, culminating in the final seconds before liftoff at T-0. These final seconds involve checks and verifications to ensure all systems are ready for launch.

Its 3.0 m/s acceleration = (final_speed − initial_speed) / time_interval Solve the above for "final speed." They give you all the other quantities, so just plug them in. (Remember that "deceleration" means the acceleration is negative.
