Day 3

1A spring of spring constant 200N/m is compressed by 5cm and used to launch a ball of mass 0.1kg horizontally off a table.The table is 1m high.What is the maximum horizontal distance that the ball can travel before hitting the ground?

2.A mass of 5kg is suspended from a spring that is hung from the ceiling.The spring streched 10cm from its original length,when mass is hung from it.The spring streched 10cm from its original length when the mass is hung from it.If the mass is pulled down an additional 5cm and released,what is the period of the resulting simple harmonic motion?

3.A particle of mass m1=2kg and M2=3kg are connected by a light string and placed on a frictionless table.A horizontal force of 10N is applied to the first block.What is the tension in the string and the acceleration of the block?

4.Aperson is standing at the edge of a cliff that is 100 meters high.They throw a ball horizontally with an initial velocity of 15m/s.How far from the base of the Cliff will the ball land,and what is the velocity just before it hits the ground?

5.Two cars are traveling in the same direction on a straight road.The first car is travelling at a speed of 20m/s,and the second car is 300 meters behind the first car,it begins to accelerate at a rate of 3m/S2.How long will it take the second car to catch up the first one?
