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.
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)
