A baboon steals an apple and runs to a nearby boulder 10.0 m to its left. The baboon reaches the boulder in 1.0s with a constant acceleration of 20.0m/s^2 leftward. What was the baboon's initial velocity when it started running to the boulder? Answer using a coordinate system where rightward is positive. Round the answer to two significant digits.

Saki is ice-skating to the left with a velocity of 5 m/s. A steady breeze starts blowing, causing Saki to accelerate leftward at a constant rate of 1.5m/s. After 6s what is Saki's velocity? Answer using a coordinate system where rightward is positive.

A car is traveling to the right with a speed of 29m/s when the rider slams on the accelerator to pass another car. The car passes in 110m with constant acceleration and reaches a speed of 34m/s. What was the acceleration of the car as it sped up? Answer using a coordinate system where rightward is positive. Round the answer to two significant digits.

4. An antelope runs with a constant velocity of 22.0 ms- by a cheetah that is lying in the grass. The cheetah gets up and begins chasing directly after the antelope just as it has gone past, with a constant acceleration of 8.60 ms2, until it reaches its top speed of 30.0 ms-. At that point the cheetah runs with constant velocity. How far does the cheetah run before it catches up to the antelope?

11.78 A car is traveling at a constant speed of 54 km/h when its driver sees a child run into the road. The driver applies her brakes until the child returns to the sidewalk and then accelerates to resume her original speed of 54 km/h; the acceleration record of the car is shown in the figure. Assuming x = 0) when t = 0, determine (a) the time t, at which the velocity is again 54 km/h, (b) the position...

7. For each of the motions below sketch a motion diagram as described in section You may use a dot to represent the object in motion. First, establish a coordinate axis for each motion. Draw arrows to scale above each dot to represent the velocity vector. Indicate the acceleration direction for each constant acceleration segment of the motion. (SC) A car is travelling at a constant speed of 35 mph when the driver sees a stop sign. The driver takes...

4) The diagrams below show a ball swinging on a string. The diagrams show the ball's position at equal time intervals. The first position is when the ball is moving up and left. Copy these into your lab notebook and then draw acceleration vectors for the ball on each one the acceleration points the way you drew it for each diagram. The arrows show the ball's relative speed and direction at each instant and turnaround points have...
