63 degrees
The term for a specific Velocity at a specific point in time
What is Instantaneous Velocity?
Two ways to name a vector lying between North and East
What is East of North & North of East?
The angular acceleration of a horizontal rotating platform with its radius r is initially at rest, and then begins to accelerate constantly until it has reached an angular velocity ω after 2 complete revolutions.
What is ω2/ 8π
The work being done on a 62kg box being pushed with a 100N force for 5m
500J
The immediate kinetic immediately before impacting the ground if it is thrown straight downward with an initial speed of 20 m/s if the object is 4kg and has a height of 10m above the Earth’s surface.
What is 1,200 J?
A kangaroo is able to jump 2.62m. Assuming it started from rest, this is the takeoff speed of the kangaroo.
What is 7.17 m/s
Two forces are applied on a mass over a frictionless surface. The acceleration of the block is 2 m/s^2. F1 = 12N to the left / F2 = 2N to the right
What is 5kg
The amount of power needed to get rid of the wheel’s energy when it is a horizontally-mounted disk with moment of inertia I spins about a frictionless axle. At time t=0, the initial angular speed of the disk is ω . A constant torque τ is applied to the disk, causing it to come to a halt in time t.
What is Iω2/2t
The mass of a block when a man does 350J of work while pulling a box from the ground up to his roof at a constant speed. The roof is 4.0m above the ground.
