A space vehicle accelerates uniformly from 85 m/sm/s at tt = 0 to 167 m/sm/s at tt = 10.0 ss . How far did it move between tt = 2.0 ss and tt = 6.0 ss ?

An object's position in the  as a function of time obeys the equation;  x(t) = 14.2/t2.17 + 5.1t3 where all constants have proper SI Units. What is the speed of the object in the x direction at t = 1.93 seconds?

Nerve impulses in a human body travel at a speed of about 100 m/s. Suppose a person accidentally steps barefoot on a pebble. About how much time does it take the nerve impulse to travel from the foot to the brain (in s)? Assume the person is 1.60 m tall and the nerve impulse travels at uniform speed.

A spaceship is traveling at a constant velocity of v ⃗ (t) = 250.0i ^ m/s when its rockets fire, giving it an acceleration of a ⃗ (t) = (3.0i ^ + 4.0k ^ )m/s2. What is its velocity 5 s after the rockets fire?

1.A spacecraft starts from rest, and makes a journey to a destination 258000 km from its starting point. It does so by accelerating at a constant rate of 11.65 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 11.65 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take?     2 hr 37 min     1 hr 51 min     6 hr 9 min     3 hr 5 min   2. An unidentified flying object (UFO) is observed to travel a total distance of 47000 m, starting and ending at rest, over a duration of 1.18 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2.     6,882 g s     135,019 g s     67,509 g s     13,763 g s   3. A Ford passes a Toyota on the road (both vehicles are traveling in the same direction). The…

You step onto a hot beach with your bare feet. A nerve impulse, generated in your foot, travels through your nervous system at an average speed of 139m/s. How much time does it take for the impulse, which travels at a distance of 1.81m, to reach your brain?

I had a dream last night that I was chased by my teddy bear. In my dream, I was sleepwalking at a constant velocity of 60ft/sec. At exactly 4:00 am I noticed my teddy bear standing 1000 feet behind me. At that instant I began to accelerate at 10 ft/sec/sec and the teddy bear began to accerlate after me at 12 ft/sec/sec. At the moment the bear caught up to me, I woke from my dream in a cold sweat. To the nearest second, What time was this?

A spacecraft starts from rest, and makes a journey to a destination 220000 km from its starting point. It does so by accelerating at a constant rate of 7.51 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 7.51 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take?

Two-dimensional motion: Object A has a position as a function of time given by rA(t) = (3.00 m/s)t i + (1.00 m/s2)t2j. Object B has a position as a function of time given by r p(t) = (4.00 m/s)ti + (-1.00 m/s2)t2i. All quantities are SI units. What is the distance between object A and object B at timet= 3.00 s?
