Mu'tah University Department of Physics General Physics 101 Summer Semester Home Work (1) 1) If x and t represent distance and time, respectively, what is the dimension of C in the relation x=1/2 C²? 2) If A-40 and B-50 as shown, what is the magnitude of vector C, if C-A-B? 3) If A-12-16) and B=-247 +10), what is the magnitude of a vector C if C-2A-B? 4) In the previous problem, what is the direction of? 60° 5) The position of a particle moving along the x axis is given by x=21-241, what is the magnitude of the acceleration of the particle when the particle is not moving? 6) A ball thrown upward vertically (S)from the ground level is caught() 3 s later by a person on a balcony which is 14 m above the ground. Determine the initial speed of the ball. 7) A particle starts from the origin at t=0 with a velocity of 8 m/s and moves in the xy plane with a constant acceleration of 41 +27 m/s². At the instant the x coordinate of the particle is 29m, what is the value of its y coordinate? 8) An airplane flies horizontally (l) with a speed of 300m/s at altitude (E) of 400m. What horizontal distance from a target () must the pilot release a bomb so as to hit () the target? 9) An object moving at a constant speed requires 6s to go once around a circle with a radius of 2m. What is the magnitude the instantaneous acceleration of the particle during this time? 10) At 10, a particle is located at x=25 m and has a velocity of 15 m/s in the positive x direction. The acceleration of the particle varies with time as shown in the diagram. What is the position of the particle at t=5s? 4,(m/s²) 3 0 3 61(s)
