Mass = ___________ Acceleration = ___________ Time = ___________ Velocity = ___________ Force = ___________ Momentum = ___________ Distance = ___________ Energy = ___________ Speed = ___________ D) Physics Problems What is the net force acting on the following force diagrams? 5N 7N 2N 5N 12N Force: A 12 kg book is accelerated across a desk at 50 m/s2. What was the force given to the book? Acceleration: A car traveling 22 m/s notices a deer in the middle of the road and comes to a stop to avoid hitting it. If this takes 7 seconds, what is the car’s acceleration? Velocity: A skateboarder is traveling at a rate of 14m/s down a ramp. If he travels 9 meters how long will it take him to get to the end of the ramp? Momentum: A football with a mass of 0.88kg is thrown at a rate of 17 m/s, and a baseball with a mass of 0.93 kg is thrown at a rate of 91 m/s. Which object has a greater momentum? Distance/Displacement: A block is moved 895 meters forward and then 899 meters backward. What is the block’s total distance and displacement? Distance = _________________________ Displacement = __________________________ Conservation of Momentum: An 6 kg toy train moving at 10 m/s slams into a stationary 20 kg toy boxcar. What is the velocity of the two if they stick together after the collision? Energy: What is the mass of a wood crate resting on a ledge with 89,000 J of PE at a height of 7 meters? Conservation of Energy: A 2 kg ball was rolled down the ramp. At point A it has a velocity of 4 m/s. Consider the situation to be completely frictionless and no other outside forces are acting on the ball as it rolls down the ramp. Answer the questions below based off the data shown within the picture. 1) What is the PE and KE at all 4 points? A) PE = ____________ B) PE = ____________ C) PE = ____________ D) PE = ____________ 2) How fast is the ball going at Point B?__________ 3) How fast is the ball going at point D? __________ 4) At what height would the ball be going 8m/s? __________ KE = ____________ KE = ____________ KE = ____________ KE = ____________
