# A projectile is shot from the ground at a velocity of #2 m/s# and at an angle of #(2pi)/3#. How long will it take for the projectile to land?

To find the time it takes for the projectile to land, you can use the formula: ( t = \frac{2v_0 \sin(\theta)}{g} ), where ( v_0 ) is the initial velocity (2 m/s), ( \theta ) is the launch angle ((2π)/3), and ( g ) is the acceleration due to gravity (approximately 9.8 m/s^2). Plugging in the values, you'll get ( t \approx 0.408 ) seconds.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- If an object with uniform acceleration (or deceleration) has a speed of #12 m/s# at #t=0# and moves a total of 22 m by #t=4#, what was the object's rate of acceleration?
- The position of an object moving along a line is given by #p(t) = cos(t- pi /2) +2 #. What is the speed of the object at #t = (2pi) /3 #?
- A person observes fireworks displays from the safe distance of 0.750 meters. Assuming that the sound travels at 340 meters per second in air. What is the time between the person seeing and hearing the fireworks explosion?
- If a car travels 200 km at an average velocity of 40 km/hr, and a second car starting 1.0 hour later arrives at the 200 km destination at the same time, what is the average speed of the second car?
- A projectile is shot from the ground at a velocity of #28 m/s# and at an angle of #(pi)/2#. How long will it take for the projectile to land?
