SCI212E Physics

For this homework, carefully consider Examples 3.4 and 3.5 from the textbook, root in the individuality 3.4, Projectile Motion:

Now fruit on them delay divergent primal speed:

v0 = 100 m/s

at an prepossession 45o overhead horizon.

Use g = -10.0 m/s as the gravitational succor instead of g = -9.8 m/s.


In other language, fruit on the subjoined problems.

[1] During a fireworks unfold, a shell is shot into the air delay an primal press of 100 m/s at an prepossession of 45.0º overhead the tasteless, as illustrated in Figure 3.38. The consolidate is aged to brand the shell exact as it reaches its primary apex overhead the basis. (a) Calculate the eminence at which the shell explodes. (b) How abundantly age passed betwixt the hurl of the shell and the outburst? (c) What is the tasteless demolition of the shell when it explodes?

[2] Kilauea in Hawaii is the world’s most once erratic volcano. Very erratic volcanoes characteristically extrude red-hot buffets and lava rather than steam and ash. Suppose a enlightened buffet is extrudeed from the volcano delay a press of 100 m/s and at an prepossession 45.0º overhead the tasteless, as professionn in Figure 3.39. The buffet strikes the cause of the volcano at an eminence 20.0 m inferior than its starting apex. (a) Calculate the age it takes the buffet to flourish this track. (b) What are the majority and tendency of the buffet’s speed at application?

Again, use g = -10.0 m/s.

Please profession all your fruit, not exact the answers. Don’t learn the alienate units for all cases.
