- A big boulder has a mass of 8.20t (metric tons) and rests at a coal mine site. The boulder is blown up with explosives into 3 parts, all the 3 parts move horizontally in the xy plane. The biggest part (mass 3.3 t) travels west at a speed of 3m/s. The second part (mass 2.7t) moves at 2m/s in a direction 25.0 degrees south of east. What is the speed and direction of the third boulder part?In this question the unit vectors i and j are in the directions east and north respectively. A particle R of mass 2kg is moving on a smooth horizontal surface under the action of a single horizontal force FN. At time t seconds, the velocity vms of R, relative to a fixed origin O, is given by v = (pr -31)i + (81 +q)j, where p and q are constants and p<0. (a) Given that when t= 0.5 the magnitude of F is 20, find the value of p. When t= 0, R is at the point with position vector (2i – 3j) m. (b) Find, in terms of q, an expression for the displacement vector of R at time t. When t = 1, R is at a point on the line L, where L passes through O and the point with position vector 2i - 8j. (c) Find the value of q.A mass m₁ = 4.0 kg is suspended over a massless frictionless pulley and is attached with a. massless rope to a mass on a frictionless horizontal table, mt = 2.0 kg. This mass is itself attached to another suspended mass m2 = 6.0 kg again with a massless rope over a massless and frictionless pulley.

- Let us consider the fall of a pole vaulter as a projectile once he releases the pole. The pole has a lake of 15 8 feet and once the athlete releases the pole he will find a mattress 2 feet high, 10 feet wide and 16 feet long, which protects him in the fall. If an athlete lets go of the pole when it was 13.7 ft above the ground with a speed of 15.7 ft/s at an angle of 73 degrees. Enter the horizontal distance that the athlete will travel with the indicated conditions, add the units in the resultIf one mass is much greater than the other, the larger mass stays essentially at rest while the smaller mass moves toward it. Suppose a 1.5×1013 kg comet is passing the orbit of Mars, heading straight for the 1.99×1030 kg sun at a speed of 4.5 ×104 m/s. What will its speed be when it crosses the orbit of Mercury? The orbit of Mars is 2.28×108 km, the orbit of Mercury is 5.79×107 km, and G = 6.67×10-11 N⋅m2/kg2.The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at v,2 = 17.7 m/s when the eagle swoops down, grabs the pigeon, and flies off. At the instant right before the attack, the eagle is flying toward the pigeon at an angle 0 = 38.3° below the horizontal and a speed of vi1 = 36.7 m/s. What is the speed of the eagle immediately after it catches its prey? speed: m/s What is the magnitude of the angle, measured from horizontal, at which the eagle is flying immediately after the strike? magnitude of angle:
- You are working part-time for the GT Sports Media Complex, editing video for the women’s softball team. In one particular clip, a GT player hits a home run over the center field fence. The ball leaves the bat at a height of 4 ft, and crosses the outfield fence (220 ft away) at a height of 10 ft. Logs of the game indicate that the pitch was clocked at 68 mph as it reached the plate. Your frame-by-frame analysis of the 30-frame-per-second video indicate that the ball spent only a single frame in contact with tha bat, and another 126 frames travelling to the outfield fence. A quick internet seach tells you that a typical college softball weighs 0.4 lb. How many pounds of average force act on the ball during ocntact with the bat?Please help1 kg projectile is launched at 30 m/sec, 60 degrees from horizontal. Find speed after 2 sec.
