Two marbles are launched at t = 0 in the experiment illustrated in Figure 4-29 . Marble 1 is launched horizontally with a speed of 4.20 m/s from a height h = 0.950 m. Marble 2 is launched from ground level with a speed of 5.94 m/s at an angle θ = 45.0° above the horizontal. (a) Where would the marbles collide in the absence of gravity? Give the x and y coordinates of the collision point. (b) Where do the marbles collide given that gravity produces a downward acceleration of g = 9.81 m/s 2 ? Give the x and y coordinates.

A particle moves down a horizontal route that begins 5 feet to the right of a specific point P with an initial velocity of 4 feet per second. Another particle is going along the same route, beginning 3 feet to the left of P with an initial velocity of 8 feet per second. Consider that the accelerations of the two particles are a1(t) = 2t 3 and a2(t) = 2t 5, respectively. Will the particles collide? Justify your response
A spacecraft is observed to be at a location < 200 , 300 , -400 > m relative to an origin located on a nearby asteroid, and 5 seconds later is observed to be at location < 340 , 80 , -540 > m.
(a) What is the average velocity of the spacecraft during this interval?v→avg = m/s
(b) What is the average speed of the spacecraft during this period?|v→avg|= m/s
