1. /A (1.0) kg cart moves on a straight horizontal track. The graph of velocity v versus time t for (4) On the axes below, sketch the acceleration a jesus time ( graph for the motion of the cart from 1 0 to 1-25s he cart is given below. er (m/sz ) w, (mis) 1.0 0.8 0.6 0.6 0.4 0.4 0.2 0.2 25 -0.2 -0.4 -0.6 -0.6 -D.B -0.8 -1.0 - 1.0 K (5) For what time(s) is the acceleration of the object greatest? (1) on the axes below, sketch the distance d versus time t graph for the motion of the cart from 1=0 to 1=25s dim) (6) For each section, find the net force acted to the cart. -15 1 12 2 2 4 1 3 54 (7) From t= 25 s until the cart reaches the end of the track, the cart continues with constant horizontal velocity. The cart leaves the end of the track and hits the floor, which is 0.10 m below the track. Neglecting air resistance, determine each of the following: (2) At which time is the car the greatest distance from the origin? L The time from when the cart leaves the track until it first hits the floor. 105 is the zar the greatest distance from the Drain . it, The horizontal distance from the end of the track to the point at which the cart first hits the floor. y= Vo+at We can change this breaks to Vo = LOT- V. + = 25 (3) What is the maximum displacement from start for the toy car? He maximum asplacement mmm wort or the toy for
