Q. An arrow is shot at an angle of theta = 45^circ above the horizontal. The arrow hits a tree a horizontal distance D = 220 ; {rm m} away, at the same height above ground as it was shot. Use g = 9.8 ;{rm m/s^2} for the magnitude of the acceleration due to gravity. Find t_a, the time that the arrow spends in the air.
Assume someone drops an apple from a vertical distance of 6.0 meters, directly above the point where the arrow hits the tree.
How long after the arrow was shot must the apple be dropped, in order for the arrow to pierce the apple as the arrow hits the tree?
Compute the average intensity
A box weighing 300N is shoved across the floor of an apartment by a force of 400 N exerted downward at an angle of 35.2° below the horizontal. If the coefficient of kinetic friction between the box and the floor is 0.540, how long does it take to mov..
A disk of radius R = 9 cm is pulled along a friction less surface with a force of F = 15 N by a string wrapped around the edge. At the instant when d = 28 cm of string has unwound off the disk, what is torque exerted about the center of the disk.
An electric motor rotating a workshop grinding wheel at a rate of 9.90 x 10^1 rev/min is switched off. Assume the wheel has a constant negative angular acceleration of magnitude 1.70 rad/s2.

W hat is the velocity of the gasoline in the tube
The lines in a grating are uniformly spaced at 1520nm. Analyse the angular separation of the second order bright fringes between light of wavelength 603nm and 615.4 nm. Reply in units of mrad.
The wind exerts a force of 325N north on a sailboat, while the water exerts a force of 425 N west on the sailboat. Find out the magnitude and direction of the net force on sailboat.
What is magnitude of the gravitational attraction
A worker pulls horizontally on a crate on a rough horizontal floor, causing it to move forward with constant velocity. In the figure, force is the pull of the worker and force is the force of friction due to the floor.
What would be the potential difference VC - VB across the thin resistor if the battery emf is 4.00 volts? Suppose that the electric field in the thick wires is very small (so that the potential differences along the thick wires are negligible)
