The mass of the firework 4kg iv. The masses of the three fragments 1kg, 2kg, 1kg v. The velocity of the northbound fragment after the explosion 8mls vi. The velocity of the n
You are not on earth. You shoot a firework into the air. It reaches a certain peak height and then
explodes into three pieces. One fragment travels exactly north. A second fragment travels
exactly northwest.
(a) Choose values for the following. None of them can be 0.
i. The value of gravitational acceleration on this planet 10mls²
ii. The velocity of the firework as it leaves the ground 10mls
iii. The mass of the firework 4kg
iv. The masses of the three fragments 1kg, 2kg, 1kg
v. The velocity of the northbound fragment after the explosion 8mls
vi. The velocity of the northwest-bound fragment after the explosion 8mls
(b) Draw the following four photos.
i. Photo 1 is a side view of the launch of the firework.
ii. Photo 2 is a top (bird’s-eye) view of the firework just before the explosion.
iii. Photo 3 is a top (bird’s-eye) view of the firework just after the explosion.
iv. Photo 4 is a side view of the fragments as they land.
(c) Label the origin and axes on photo 1 and photo 3. You will need x, y and z axes for this
question.
(d) Calculate the peak height of the firework.
(e) Calculate the velocity of the third fragment after the explosion.
(f) Calculate where each fragment lands.
