you drop your phone while in the bathroom in front of the mirror while the water is running in the sink below. If you are .45 Meyer above the sink, how long do you have before your cell phone is a goner.
A girl sits at a distance of 12.0 m from the axis of merry-go-round in an amusement park. If the merry-go-round makes 3 rev
in 12 Os find the (a) tangential speed and (b) centripetal acceleration of the child.
A child sits at a distance of 5.0 m from the axis of merry-go-round in an amusement park. If the merry-go-round makes 2 rev
in 10.0s, find the (a) tangential speed and (b) centripetal acceleration of the child.
A car 2000kg tied to the rope of 15m whose end is located at the center. If the car is moving at the rate of 8 m/s. Calculate the centripetal force acting on it?
A 2.00-kg block is held in equilibrium on an incline of angle θ = 60.0° by a horizontal force F applied in the direction shown below. If the coefficient of static friction between block and incline is μs = 0.300,
find the magnitude of F .
A wheel 2.00 m in diameter lies in a vertical plane and rotates with a constant angular acceleration of 4.00 rad/s2. The wheel starts at rest at t = 0, and the radius vector of a certain point P on the rim makes an angle of 57.3 with the horizontal at this time. At t = 2.00 s, find (a) the angular speed of the wheel, (b) the tangential speed and the total acceleration of the point P, and (c) the angular position of the point P.
Two spherical objects have masses of 66g and 35 g. The gravitational attraction between them is 6.5 x 10-3 N. How far apart are their centers?
A hammer head, with a mass of 10.0 kg, strikes a nail at a horizontal velocity of 12.2 m/s and comes to rest in a time interval of 0.004 s. Find the impulse imparted to the nail and the average force the hammer exerted on the nail?
Rich Gossage set a fastball record by hurling a 0.14 kg baseball at a speed of 46.3 m/s. What was the magnitude of the ball’s momentum as it left his hand? *
What is the mass of a bus moving at a velocity of 110 kph if it has to fully stop before an intersection if a 7000-N of force is applied on it in 15 seconds? *
