- The particle travels along the path defined by the parabola y = 0.5x^2. If the component of velocity along the x axis is vx = (2t) m/s, where t is in seconds, determine the components of its acceleration when t = 1 s.arrow_forwardThe motorcycle is traveling at a constant speed of 60 km/h. Determine the magnitude of its acceleration when it is at point A.arrow_forwardThe ball at A is kicked such that θA = 30. If it strikes the ground at B having coordinates x = 15 ft, y = -9ft, determine the speed at which it is kicked and the speed at which it strikes the ground.arrow_forward
- Q1.If the speed of the motorcycle is v=√(600-0.5s2) where s is in meters measured from A, determine its tangential velocity, tangential acceleration and normal acceleration when it reaches B. Clearly draw free body diagram and mention velocity and acceleration vectors along with their magnitudes and angles with positive t-axis. Where r = 60m and Ɵ is 30 degrees.arrow_forwardA particle travels along the curve from A to B in 1 s. If it takes 3 s for it to go from A to C, determine its average velocity when it goes from B to C.arrow_forwardThe box slides down the slope described by the equation y = (0.02x2)m, where x is in meters. Given that the vx = -3 m/s, ax = -1.5 m/s2 at x =5 m. Determine the y components of the velocity and the acceleration of the box at x = 5 m.arrow_forward
- A freight train travels at v = 60(1-e-t) ft/s, where t is the elapsed time in seconds.Determine the distance traveled in three seconds, and the acceleration at this time. Draw the necessary diagrams.arrow_forwardThe car travels along the circular path at a speed v = (0. 8 t) m/s,where t in seconds. Determine the magnitudes of its velocity andacceleration after the car has traveled s = 20 m starting from rest.arrow_forwardIf a particle moves along a path such that r= (2 cos t) ft and θ= (t/2) rad, where t is in seconds, plot the path r =f(θ) and determine the particle's radial and transverse components of velocity and acceleration.arrow_forward
- A freight train travels at v = 60(1- e ^-t) ft/s, where t is the elapsed time in seconds. Determine the distance traveled in three seconds, and the acceleration at this time.arrow_forwardAs a train accelerates uniformly it passes successive kilometer marks while traveling at velocitiesof 3 m/s and then 12 m/s. Determine the train’s velocity when it passes the next kilometer markand the time it takes to travel the 2-km distance.arrow_forwardA certain particle travels straight at a speed of 1000 km/s. If this particle passes the point A(3,5,7) to B( 10,8,12). Determine the component of its velocity. *arrow_forward
