One strategy in a snowball fight is to throw a snowball at a high angle over level ground. Then, while your opponent is watching that snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume both snowballs are thrown with a speed of 25.0 m/s. The first is thrown at an angle of 70.0 with respect to the horizontal. (a) At what angle should the second snowball be thrown to arrive at the same point as the first? (b) How many seconds later should the second snowball be thrown after the first for both to arrive at the same time?
After a ball rolls off the edge of a horizontal table at time t = 0, its velocity as a function of time is given by v=1.2i9.8tj where v is in meters per second and t is in seconds. The balls displacement away from the edge of the table, during the time interval of 0.380 s for which the ball is in flight, is given by r=00.3803vdt To perform the integral, you can use the calculus theorem [A+Bf(x)]dx=Adx+Bf(x)dx You can think of the units and unit vectors as constants, represented by A and B. Perform the integration to calculate the displacement of the ball from the edge of the table at 0.380 s.
Solve the following linear combinations of vectors. 3.) Let us consider u= (-2,2) and v = (2,3), calculate what is obtained when performing 3u+4v. 4.) Let us consider u= (4,-6) and v = (-1,3), calculate what is obtained when performing 4u+3v. 5.) Let us consider u= (-3,-8) and v = (8,3), calculate what is obtained when performing 2u+2v
I am working on finding the inital velocity of a class II projectile and am having trouble determining the right amount of sig figs. The taken measurements of the initial position of x goes to 4 sig figs, as well as the final position for y. With that being said, I am trying to find the initial velocity of x and y separately through trionometry. For example, if I have an equation for the initial velocity of x with an angle of 40, then Vox=Vocos40 My question is, since the measured value for my angle is two significant figures, is my answer Vox=.76Vo also in two sig figs because it goes by the two significant figures from my measured angle, or should I go to four significant figures to match my measured values for x and y?

Assume both snowballs are thrown with a speed of 25.0 m/s.

Assume air resistance is negligible. b) How many seconds later should the second snowball be thrown after the first for both to arrive at the same time?
Suppose that Nolan throws a baseball to Ryan and that the baseball leaves Nolan's hand at the same height at which it is caught by Ryan. If we ignore air resistance, the horizontal range r of the baseball is a function of the initial speed v of the ball when it leaves Nolan's hand and the angle θ above the horizontal at which it is thrown. Use the accompanying table and the equations below to estimate the partial derivatives. fx(x0,y0)= limΔ⁢x→0f(x0+Δ⁢x,y0)-f(x0,y0)Δ⁢x; fy(x0,y0) =limΔ⁢y→0f(x0,y0+Δ⁢y)-f(x0,y0)Δ⁢y Take a left-hand estimate and a right-hand estimate in each case and give the average of the two as your final answer.(a) Estimate the partial derivative of r with respect to v when v=80ft/s and θ=45∘.

a. Two vectors A and B are given at a point P(r, Ɵ, Φ) in space as A = 10ar + 30aƟ – 10a Φ B = 3ar + 10aƟ – 20a Φ The scalar component of A in the direction of B The vector projection of A in the direction of B and A unit vector perpendicular to both A and B. Repeat the above solution if the two vectors A and B given at a point P(r, Ɵ, Φ) in space reduced by 30 percent. Discuss the differences in solution a and b above.
The speed of a projectile when it reaches its maximumheight is one-half its speed when it is at half its maximumheight. What is the initial projection angle of the projectile? Answer : 67.8 degrees
According to the Guinness Book of World Records the longest home run evermeasured was hit by Roy “Dizzy” Carlyle in a minor league game. The ball travelled188 m (618 ft) before landing on the ground outside the ballpark. (a) Assuming theball’s initial velocity was in the direction of 450 above the horizontal and ignoringresistance, what did the initial speed of the ball need to be to produce such a homerun if the ball was hit in a point 0.9 m above ground level? Assume that the groundwas perfectly flat. (b) How far would the ball be above a fence 3.0 m high the fencewas 116 m from home plate?
