Homework Statement
:A body is projected with 50m/sec at an angle of 53 degree with the horizontal. After what time velocity makes an angle 33.7 degree with horizontal. (tan 33.7 = 2/3)[/B]
Yep, that worked! I've got 2 seconds as the answer and hopefully it must be correct. Thanks :-)Adrian Jimenez said:Take into consideration that the motion consists of both x and y components (x=vcosθ and y=vsinθ). Perhaps you could try calculating what the initial speed and final speeds are for the y component. Then try calculating how much time it would take for that change in speed using your other kinematics formulas.
I confirm 2 sec. (More precisely, 2.03, using 9.8 for g.)dahano said:Yep, that worked! I've got 2 seconds as the answer and hopefully it must be correct. Thanks :-)
The formula for finding velocity using given angle is v = d / t, where v is velocity, d is distance, and t is time. This formula is known as the average velocity formula.
Yes, as long as you use the same unit for both distance and time, you can use any unit of measurement. For example, if you use meters for distance, you should also use seconds for time.
To find the angle, you can use the inverse tangent function (tan^-1) on a calculator. The formula would be tan^-1 (v / d), where v is velocity and d is distance. This will give you the angle in radians, so you may need to convert it to degrees if necessary.
Yes, the formula for finding velocity using given angle can be used for any type of motion, as long as the motion is linear (moving in a straight line) and at a constant speed.
No, the direction of the motion is not needed to find velocity using given angle. The formula only considers the distance traveled and the time it took to travel that distance.
