A pickup truck starts from rest and maintains a constant acceleration After a time to the truck is moving with speed 25's at a distance of 120 m from its starting point When the truck has travelled a distance of 60 m from its starting point its speed is 1) Which of the following statements concerning is true? ON 125 mis - 125 ON 125ms 2) When the truck has travelled for a time to -12 is distance from its starting point is Which of the following statements concering 52 is true? 3) How long does it take for the pickup to reach its speed of 25 mise 06-685 06965 The next two questions concem the graph shown below. This graph shows the one-dimensional velocity of a cart, as a function of time. The cart started its motion from restat position 4) Which of the following statements about as the acceleration of the cart attimet - 257, is >0 Which of the following statements about the position of the cart at time-3 is true OxO Two b each capable of moving is still wara a constant city - 6ms out to crossa river of width W-20 Boat leads directly across the river while bout 2 is pointed at an angle - 60 degrees with respect to the shore as shown in the diagram below. The current in the river move a podo-2 as shown. The next three questions pertain to this situation W 6) Which boat takes the least amount of time to cross the river? Boat takes the least time Boat takes the least time Each boat takes the same amount of time.
7) Which boat moves with the greater speed with respect to the short Boat I moves with the greater speed with respect to the shore Boat 2 moves with the greater speed with respect to the shore They both move at the same speed with respect to the shore %) How far downstream (D) is beat 2 when it reaches the other side of the river? OD 7.1 m OD=79m OD 100 m OD 146 m OD-19.3 m Two projectiles are launched from a cliff of height -16m as shown in the diagram below Projectile I is launched with velocity v1 - 12 ms at an angle Q1, where Q1 - 35 degrees. Projectile 2 is launched with velocity v2-12 m/s at an angle Q2, where 92 - 50 degrees. The next six questions pertain to this physical situation 9) If the projectiles are lached at the same time, which projectile lands first? Projectile I lands first Projectile 2 lands first The projectiles and at the same time 10) What is the maximum height of projectile 2 above the ground from the top of the clit) Oy 7.9 m 11.3 m Oy203 m Oy - 260 m Oy 38.4 m 11) At the top of projectile 2's path, what is its speed? OY-Oms OY 5.6 ms QY7.7m's Ov=9.8 m's OY-12.0 m's 12) How far from the cliff does projectile 2 land from the base of the clair OX-19.1 m 12.9 m O 27.5 m O -30.1 m OX31.3 m 13) Right before projectile 2 hits the ground, what is its speed Om's Ov12.0 m/s OY-18.7 m's OY 21.4 m/s 30.3 ms 14) Which projectile lands farther away! Projectile lands farther away. Projectile 2 lands farther away. The projectiles and at the same distance from the chill 15) Acar's initial velocity is along the-x (negative x) direction. As it slows to a stop its acceleration: STO points in the points in the direction direction
