The question does not specify how many seconds it accelerates for so I would suggest that the answer is 300,000 km per second (approx).
Takes her 60 seconds to do what? Travel 1 mile? Travel 10 miles?
7.5
The answer will depend on its acceleration.
Without knowing some of the conditions that led up to the situation at 9 seconds, I'm afraid there's no way to figure that out. By the way, once you know the 'velocity', you know the 'direction'. 'Velocity' means speed and direction. It's not just a big technical-sounding word for 'speed'.
0.8633 seconds
Apply to the equation V=U+at . The answer is 40.
Given: V0 = 24 m/s, a = 2 m/s2, t = 8 s. (a = acceleration, t = time) Vf = V0 + a t Vf = (24) + (2) (8) = 24 + 16 = 40 m/s.
Given: V0 = 24 m/s, a = 2 m/s2, t = 8 s. (a = acceleration, t = time) Vf = V0 + a t Vf = (24) + (2) (8) = 24 + 16 = 40 m/s.
It's zero
you doing homework???
One example problem of speed and velocity would be 'What is the speed of a sailboat traveling 100 meters in 180 seconds?' You can use a calculator to solve these types of problems.
Velocity (Speed) = Distance ÷ Time, therefore Time = Distance ÷ Velocity. Time = 4620 ÷ 4 = 1155 seconds = 19 minutes 15 seconds
19 - 89 = -70 -70/7 = -10 It accelerated at -10 m/s^2
Velocity increases after 5 seconds
Speed= Distance / time => Distance = Speed x Time =16x8 = 128m
Absolutely! If an object has been already traveling for 30 seconds. If you start your watch at 30 seconds, then t = 0 at 30 seconds! The velocity of the object 3 seconds BEFORE you start the watch would then be t = -3 and 3 seconds after you start the watch would be t = 3.
Velocity is derived by dividing displacement with time in seconds
