What is the shape of projectile?
Any shape you like. A stone that is thrown is a projectile. A cannonball, arrow, spear, bullet are all projectiles. A projectile s an object all of whose momentum comes at the moment of launch; once it is launched, it travels under that initial momentum and external forces such as gravity and air resistance. There is no "on board" rocket or other means of propulsion.
An angle measures 31 degrees What is the measure of its supplement?
A supplement of an angle is the angle that we add to the initial angle and have a result of 180 degrees. The supplement of 31 degrees is 180-31=149 degrees.
Suppose a rock is dropped off a cliff with an initial speed of 0 ms What is the rock's speed after 3 seconds in ms if it encounters no air resistance?
29.4
What angle is coterminal with 30 degrees?
An angle that is coterminal with 30 degrees can be found by adding or subtracting multiples of 360 degrees. In this case, an angle coterminal with 30 degrees could be 390 degrees (30 + 360) or -330 degrees (30 - 360). Coterminal angles have the same initial and terminal sides, but may differ in number of rotations around the unit circle.
How long will it take ball that is dropped from a 324 foot tall building to hit the ground?
Assuming that air resistance can be ignored, s = ut + 0.5gt2 where s is the distance travelled = 324 feet, u is the initial velocity = 0 ft/sec, t is the time (in seconds), and g is the acceleration due to gravity = 32 ft/sec2 Therefore 324 = 0.5*16*t2 so that t2 = 20.25 and so t = 4.5 seconds.
What forces stop a moving cannonball from reaching outer space?
The forces that stop a cannonball from reaching outer space include gravity, air resistance, and possibly drag forces. Gravity pulls the cannonball back towards the Earth, while air resistance and drag forces slow it down as it travels through the atmosphere. These forces oppose the initial velocity and energy of the cannonball, preventing it from escaping Earth's gravitational pull.
A cannonball shot with an initial velocity of 141ms at an angle of 45 degrees hits a balloon at the top of its trajectory Neglecting air resistance how fast is the cannonball going?
If it is at the top of its trajectory, all of its initial upward velocity is gone and it is traveling horizontally at about 100 m/sec, the original portion of its velocity. cos45 = sin 45 = 0.707 141 x .707 = 99.7 (close to 100 for the whole value given)
What is an initial speed of a cannonball?
Depends on the cannon and the charge.
When are final and initial velocities taken ball kicked at 30 degrees at 10ms?
Initial velocity is 10 m/s in the direction it was kicked. Final velocity is 0, when friction and air resistance finally causes it to come to a halt.
How far does a projectile travel if you launch it at 30 degrees versus if you launch it at 60 degrees?
Assuming the angle is the angle the initial trajectory makes with the ground, that it's launched with the same speed in both cases, that it's launched from an initial height of zero, that it stops dead as soon as it touches the ground and doesn't bounce or roll, and that we can neglect air resistance (sorry for all that detail, but it does matter)... Both projectiles will end up with the same net displacement, though the 60 degree projectile will have taken a longer path to get there.
Will cannonball travel farther if shot from a longer cannon. why?
Yes, a cannonball will generally travel farther if shot from a longer cannon. A longer cannon gives the cannonball more time to accelerate and build momentum before exiting the barrel, resulting in a higher initial velocity and longer travel distance.
What is initial primary resistance?
initial primary resistance is the first stage in revolt against the initial imposition of colonial rule. the africans ready resisted the ,imposition of colonial rule. they did not give the europeans the chance to impose their colonial policies.
Suppose a rock is dropped off a cliff with an initial speed of 0ms. what is the rocks speed after 5 second in ms if it encounters no air resistance?
The speed of the rock after 5 seconds, neglecting air resistance, can be determined using the equation: speed = initial velocity + acceleration * time. Since the initial speed is 0 m/s, and assuming the acceleration due to gravity is 9.81 m/s², the speed of the rock after 5 seconds would be 49.05 m/s.
What is base timing on a 1970 Pontiac 350?
Assuming you are running a point type distributor a Pontiac typically likes 12-14 degrees initial advance. This is also a good starting point for HEI.
If i have the initial and after temperature how would i be able to find the change in temperature?
You can find the change in temperature by subtracting the initial temperature from the final temperature. For example, if the initial temperature is 20 degrees Celsius and the final temperature is 30 degrees Celsius, the change in temperature would be 10 degrees Celsius (30 - 20 = 10).
What is correct timing for 1979 403 trans-am?
The Oldsmobile engines typically had a fairly high initial timing....coming in at 18-20 degrees before TDC. That's assuming you're talking about a fairly stock 403.
What does starting resistance refer to in the context of electrical circuits?
Starting resistance in electrical circuits refers to the initial resistance encountered by a device when it is first turned on. This resistance can affect the flow of current and the performance of the device.
