- An accelerometer record for the motion of a given part of a mechanism is approximated by an arc of a parabola for 0.2 s and a straight line for the next 0.2 s as shown in the figure. Knowing that v = 0 when t= 0 and x= 0.8 ft when t= 0.4 s, (a) construct the v-t curve for 0 ≤ t≤ 0.4 s, (b) determine the position of the part at t= 0.3 s and t= 0.2 s.arrow_forward13.4 A disk is projectedwith an initial velocity of 10m/s up an incline as shown. If pg=0.2 between the disk and the incline determine (a) the maximum distance L which the disk will travel up the incline, and (b) the speed of the disk as it slide back through the original providence.arrow_forwardDuring a flyby of the earth, the velocity of a spacecraft is 10.4 km/s as it reaches its minimum altitude of 990 km above the surface at point A. At point B the spacecraft is observed to have an altitude of 8350 km. Determine (a) the magnitude of the velocity at point B, (b) the angle φB.arrow_forward
- A long-range ballistic trajectory between points A and B on the earth’s surface consists of a portion of an ellipse with the apogee at point C. Knowing that point C is 1500 km above the surface of the earth and the range Rφ of the trajectory is 6000 km, determine (a) the velocity of the projectile at C, (b) the eccentricity ε of the trajectory.arrow_forwardA child throws a ball from point A with an initial velocity v0 at an angle of 3° with the horizontal. Knowing that the ball hits a wall at point B , determine (a) the magnitude of the initial velocity, (b) the minimum radius of curvature of the trajectory.arrow_forwardA motorist is traveling on a curved section of highway with a radius of 2500 ft at a speed of 60 mi/h. The motorist suddenly applies the brakes, causing the automobile to slow down at a constant rate. If the speed has been reduced to 45 mi/h after 8 s, determine the acceleration of the automobile immediately after the brakes have been applied.arrow_forward
- A particle describes a circular trajectory with a radius of 0.4 m and its speed is constant. Knowing that it performs five revolutions per second, determine: -its speed. -its acceleration.arrow_forwardAt an intersection, car B was traveling south and car A was traveling 30° north of east when they slammed into each other. Upon investigation it was found that after the crash the two cars got stuck and skidded off at an angle of 10° north of east. Each driver claimed that he was going at the speed limit of 50 km/h and that he tried to slow down but couldn’t avoid the crash because the other driver was going a lot faster. Knowing that the masses of cars A and B were 1500 kg and 1200 kg, respectively, determine (a) which car was going faster, (b) the speed of the faster of the two cars if the slower car was traveling at the speed limit.arrow_forwardTwo hemispheres are held together by a cord which maintains a spring under compression (the spring is not attached to the hemispheres). The potential energy of the compressed spring is 120 J and the assembly has an initial velocity v0 of magnitude v0 = 8 m/s. Knowing that the cord is severed when 0 = 30°, causing the hemispheres to fly apart, determine the resulting velocity of each hemisphere.arrow_forward
