Physics Unit 6: Impulse and Momentum

L.O.: Apply Impulse and Momentum

CA standard: PH 2 d, e, f, g

Warm up: {FM} (ie from memory) write down Newton’s Law of gravitation. Sketch how you would apply this law to a ball rolling down a ramp.

 

momentum-36_sec

Draw a free body diagram, calculate the acceleration due to gravity in the rock’s direction of motion. Calculate the velocity of the rock.

Assume the rock has a mass of 10 metric tons  (1 metric ton = 1 tonnes  = 1,000kg). Assume the rock has descended 100 meters of vertical height.  (hint: estimate the angle of slope of the mountain)
