An object is pushed from rest across a sheet of ice accelerating at 5 m/s? [right] over a distance of 80 cm. + The object slides with a constant speed for 4 seconds until it reaches a rough section, which causes it to stop in 2.5 seconds. a) What is the speed of the object when it reaches the rough section? [3 marks] b) What is the object's acceleration while it is on the rough section? [3 marks] 2.

You are holding an 85 kg trunk at the top of a ramp that slopes from the back of a van to the ground, making a 350 angle with the ground. You lose your grip and the trunk begins to slide. If the coefficient of friction between the trunk and the ramp is 0.42, what is the acceleration of the trunk? [Make sure you find the value of all forces acting on the trunk] [5 marks] OneDrive ...
