3 points Save Answ Question3 t f knowm mass that is initially at rest. The projectile becomes embedded (stuck) in the hanging target. The combined target and projectile move back and up, reaching a maximum which the speed of this object is temporarily zero). This height is measured by a camera that records the event. This method is shown in the diagram. 14 cm, what was the speed of the bullet when it hit If the bullet has a mass of 22 g. the target has a mass of 2.2 kg, and the maximum height, h, reached by the target and bulet was the target, in units of m/s? 3 points Save Answer

Explanation / Answer

Total mass of pendulum = 2.2 kg + 0.022 kg = 2.222 kg

Height h = 14 cm = 0.14 m

PE = mgh = 2.222 x 9.81 x 0.14 = 3.05 J

Mass of bullet = 22 g = 0.022 kg

KE = PE

0.5 mv2 = 3.05

0.5 x 0.022 x v2 = 3.05

v2 = 277.2727

v = 16.65 m/s
