3.A missile is fired into the air at a distant target. Before reaching the target, it explodes mid-air and breaks up into two pieces, one of which has a mass of 200 g and flies off horizontally with a speed of 8.2 m/s. The second piece has a mass of 300 g and flies off vertically with a speed of 4.5 m/s. What was the initial velocity of the firecracker?
A.72 m/s, 56 degrees from the horizontal
B.18.7 m/s, 29 degrees from the horizontal
C.4.2 m/s, 39 degrees from the horizontal
D.21.2 m/s 56 degrees from the horizontal

PHYSICS 30 MOMENTUM AND IMPULSE Q9 ASSIGNMENT A. MOMENTUM AND IMPULSE a. C. 1. Use the concept of Impulse to describe one advantage of seatbelts. 2. A 5.00 kg mass is moving with a velocity of 3.50 m/s. A force of 4.00 N acts on the object increasing its velocity (in the same direction) to 12.5 m/s. Determine Change in momentum b. Impulse the mass experiences Time interval that the force was applied for 3. A 15.0 kg object is...
1. A train at a constant 62.0 km/h moves east for 32.0 min, then in a direction 46.0° east of due north for 29.0 min, and then west for 42.0 min. What are the (a) magnitude and (b) angle (relative to east) of its average velocity during this trip? 2. A cart is propelled over an XX plane with acceleration components ax 5.5 m/s2 and ay = -2.3 m/s. Its initial velocity has components vox = 9.3 m/s and voy...
