rate of 24.6 m/s2 after hiting the water. How far the object will go below the...
Suppose that a cart accelerates with a rate of 1.158 m/s2. After 2.09 s how far has it gone in cm? Note the units!
An object could accelerate continuously at 10.0 m/s2, how far would it travel and how long would it take to reach: (a) the speed of sound, 334 m/s; (b) the escape speed of a rocket from the earth, 11.2 km/s; (c) 10% of the speed of light? Assume it starts from rest
A m=6 gram object is accelerated at a rate of a=3.4 m/s2. What is the magnitude of 103×F where F is force the object experience? Express the answer with one decimal place (don't forget to add the unit).
Calculate the magnitude and direction, and after .53s how far
beneath the top of the off is the stone?
From the top of a cliff, a person throws a stone straight downward. The initial speed of the stone just after leaving the person's hand is 9.8 m/s. (a) What is the acceleration (magnitude and direction) of the stone while it moves downward, after leaving the person's hand? magnitude direction m/s2 Is the stone's speed increasing or decreasing? n increasing O...
The vector position of an object varies according to r(t) = (24.0 m)i + [(2.00 m/s2)t2]j, where t is in seconds. (a) Determine the magnitude of the position vector at t = 5.00 s. (b) Determine the magnitude of the velocity vector at 5.00 s. A boy stands on a diving board and throws a stone into a swimming pool. The stone is thrown from a height of 2.93 m above the water surface with a velocity of 5.26 m/s...
How far below the water surface should a vertical square 1m on a side with two sides horizontal to be immersed so that the center of pressure will be 70mm below the center of gravity? a.) 0.69 m b.) 0.79 m c.) 0.89 m d.) 0.99 m
9.8 m/s2. Use g As shown in the figure below, object m, = 1.55 kg starts at an initial height h,= 0.310 m and speed v,; = 4.00 m/s, swings downward and strikes (in an elastic collision) object m, = 4.60 kg which is initially at rest. 4.00 m/s (a) Determine the speed of m, (in m/s) just before the collision m/s (b) Determine the velocity (magnitude in m/s and direction) of each ball just after the collision (Assume the...
A rock dropped down a well takes 1.92 s to hit the water. How far below the top of the well is the surface of the water? Note: the acceleration from gravity is 9.8 m/ Note: d = 1/2gt2n
On the Moon, the acceleration due to gravity is 1.62 m/s2 How far would a 41 g rock fall from rest in 9.5 seconds if the only force acting on it was the gravitational force due to the Moon?
5. An object is traveling at 20 m/s, but is accelerating at -5 m s2. After six seconds the object begins to slow and has come to a stop five seconds later. Draw graphs of position, velocity and acceleration versus time (each on separate axes) for this object. Be quantitative. Specify the position, velocity, acceleration and time tor point(s) when the object has stopped.
