Review Part A A speed skater moving to the left across frictionless ice at 8.5 m/s hits a 4.3-m-wide patch of rough ice. She slows steadily, then continues on at 6.1 m/s. What is the magnitude of her acceleration on the rough ice? Express your answer with the appropriate units. a= 1 Value Units Submit Request Answer
A speed skater moving across frictionless ice at 8.5 m/s hits a 5.9 m -wide patch of rough ice. She slows steadily, then continues on at 5.5 m/s What is her acceleration on the rough ice?
On an essentially frictionless, horizontal ice rink, a skater moving at 6.0 m/s encounters a rough patch that reduces her speed by 46 % due to a friction force that is 26 % of her weight. Use the work-energy theorem to find the length of this rough patch.
"On an essentially frictionless, horizontal ice rink, a skater moving at 4.3 m/s encounters a rough patch that reduces her speed by 42% due to a friction force that is 24% of her weight. Use the work—energy theorem to find the length of this rough patch."
On an essentially frictionless horizontal ice-skating rink, a skater moving at 2.8 m/s encounters a rough patch that reduces her speed by 47 % to a friction force that is 22 % of her weight. Use the work-energy principle to find the length of the rough patch.
Part C Review A 4.5 kg box slides down a 5.2-m -high frictionless hill starting from rest, across a 2.3-m -wide horizontal surface then hits a horizontal spring with spring constant 470 N/m How far is the spring compressed? Express your answer using two significant figures The other end of the spring is anchored against a wall The ground under the spring is frictionless, but the 2.3-m- long horizontal surface is rough. The coefficient of kinetic friction of the box...
Problem 11.56 A 4.5 kg box slides down a 4.3-m -high frictionless hill, starting from rest, across a 1.7-m -wide horizontal surface, then hits a horizontal spring with spring constant 550 N/m The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 1.7-m-long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.27. How far is the spring compressed? Express your answer to...
A 4.5 kg box slides down a 4.2-m -high frictionless hill, starting from rest, across a 2.2-m -wide horizontal surface, then hits a horizontal spring with spring constant 550 N/m . The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 2.2-m-long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.22. Part C How far is the spring compressed? Express your answer...
An object with cross section A is shot horizontally across frictionless ice. Its initial velocity is v0x at t0=0s. Air resistance is not negligible. A 1.8 m wide, 1.5 m high, 1700 kg car with a drag coefficient of 0.35 hits a very slick patch of ice while going 24 m/s . Air resistance is not negligible. If friction is neglected, how long will it take until the car's speed drops to 11 m/s ? To 5.0 m/s ?
