Data: Item | Value | Mass of Cart | 516g | Impulse | .35N | Velocity before | .343 m/s | Velocity after | -.318 m/s | Momentum before | .177 kg m/s | Momentum after | -.163 kg m/s | change | -.340 kg m/s | Questions: 1.Why is it desirable to have the same initial speed for each data run? If speed differs‚ the momentum will be effected. As velocity increases‚ momentum increases. 2.How will raising the end of the Dynamics Track give the cart the same

1 Introduction ANSWERS TO MULTIPLE CHOICE QUESTIONS 1. Using a calculator to multiply the length by the width gives a raw answer of 6783 m 2 ‚ but this answer must be rounded to contain the same number of significant figures as the least accurate factor in the product. The least accurate factor is the length‚ which contains either 2 or 3 significant figures‚ depending on whether the trailing zero is significant or is being used only to locate the decimal point. Assuming the length contains 3 significant

bullet of mass 10 g has a muzzle velocity of 300 m/s. Find (a) the momentum of the bullet (b) the recoil velocity of the gun if its mass is 2.0 kg. 3. A 70 kg man dives away from a stationary canoe with a velocity of 3.0 m/s parallel to the water. If the canoe has a mass of 150 kg‚ find its recoil velocity. 4. A steel sphere of mass 0.10 kg is fired horizontally with a velocity of 30 m/s into a block of plasticine of mass 1.0 kg at rest. With what velocity does the combination move away?

the characteristics of Problem Based Learning (PBL) from various literature. Problem-based learning (PBL) is an emerging teaching approach which has taken its prominence in tertiary education in recent years. PBL is an instructional strategy in which learner-centered method is adopted and students learn by working on real life problems and activities‚ where teacher acts as a facilitator (Barrows‚H & Tamblyn‚ R.M‚ 1980). It is a style of learning in which the problems act as the driving force
