1. A 3kg mass is released from rest at the top of a straight ramp Inclined at 15 degrees above the horizontal. The coefficient of static friction between the block and the incline is 0.45 and the coefficient of kinetic friction is 0.28. Will the block slip? If you answer 'yes', also give the value of the block's acceleration. If you answer 'no', also give the value of the friction force that would be on the block's free-body diagram. 2. A 2 kg block moving at a speed of 14 m/s heads up a 7-meter-tall, curved, friction-free ramp. Will the block make it to the top? If you answer 'yes', also give the speed it has on its arrival at the top. If you answer 'no', also give the maximum height it reaches. 3. A soccer ball is kicked with a speed of 20 m/s at an angle of 40' above the horizontal from ground height by a person standing 30 meters in front of a tall building. At what height above the ground will the ball hit the wall of the building? Assume there is no air resistance
