- If the displacement of a point along x-axis is u = 3 mm and the displacement along y-axis is v = 2 mm, and if “t” is an axis making an angle of 30o in the clockwise direction with respect to x-axis, what would be the displacements of this point ut and vn along the orthogonal axes “t” and “n”, respectively? Select one: ut = 3.598 mm and vn = 0.232 mm ut = 0.232 mm and vn = 3.598 mm ut = 3.232 mm and vn =1.598 mm ut = 1.598 mm and vn = 3.232 mmarrow_forwardWhat is the magnitude of a→×(b→×a→) if there is an angle φ = 23.0° between the directions of a→ and b→? Assume a = 7.9 and b = 5.1.arrow_forwardA submarine dives from the water surface at an angle of 30° below the horizontal, following a straight path 50 m long. How far is the submarine then below the water surface? (a) 50 m (b) (50 m)/sin 30° (c) (50 m) sin 30° (d) (50 m) cos 30° (e) none of those answers.arrow_forward
- Brandon is on one side of a river that is 60 m60 m wide and wants to reach a point 300 m300 m downstream on the opposite side as quickly as possible by swimming diagonally across the river and then running the rest of the way. Find the minimum amount of time if Brandon can swim at 2 m/s2 m/s and run at 4 m/s.arrow_forwardAn archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.335 m above his mouth. What angle (in degrees) above the horizontal must he spit?arrow_forwardOne strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching this first snowball, you throw a second snowball at a low angle and time it to arrive at the same time as the first. Assume both snowballs are thrown with the same initial speed 32.1 m/s. The first snowball is thrown at an angle of 57◦ above the horizontal. At what angle should you throw the second snowball to make it hit the same point as the first? Note the starting and ending heights are the same. The acceleration of gravity is 9.8 m/s 2arrow_forward
- Consider the three displacement vectors = (−2î− 3ĵ) m, = (4î − 5ĵ) m, and = (−6î + 5ĵ) m. Use the component method to determine the following. (Take the +x direction to be to the right.)arrow_forwardA landscape architect is planning an artificial waterfall in a city park.Water flowing at 0.750 m/s leaves the end of a horizontal channel at the top of a vertical wall h = 2.35 m high and falls into a pool (Fig. P3.70). (a) How far from the wall will the water land? Will the space behind the waterfall be wideenough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, one-twelfth actual size. How fast should the water flow in the channel in the model?arrow_forwardOne strategy in a snowball fight is to throw a snowball at a high angle over level ground. While your opponent is watching this first snowball, you throw a second snowball at a low angle and time it to arrive at the same time as the first. Assume both snowballs are thrown with the same initial speed 20.5 m/s. The first snowball is thrown at an angle of 68◦ above the horizontal. At what angle should you throw the second snowball to make it hit the same point as the first? The acceleration of gravity is 9.8 m/s 2 . Answer in units of ◦ .arrow_forward
- A golfer on level ground attempts to drive a golf ball across a 50 meter wide pond by hitting the ball so that it travels initially at 25m/s at an angle of 45 degrees to the horizontal plane. How far will the golf ball travel?arrow_forwardA particle is moving on top of a 2-dimensional. plane with its coordinates given in cartesian system as x(t) =a sin ωt, y(t) = a cos ωt. Express the motion of the particle in terms of polar coordinates (ρ, φ). What is the minimum number ofgeneralised coordinates required to describe. its motion? Draw the. trajectory of the particle.arrow_forwardIf A = 3i + 3j and B = 7i + 5j, what is the magnitude of C = A - Barrow_forward
