Q. A place kicker should kick a football from a point 32 m (about 35.0 yd) from the goal, and the ball should clear the crossbar, which is 3.050 m high. When kicked, the ball leaves the ground with a speed of 21.0 m/s at an angle of 49° to the horizontal.
Q. An airplane flies due south at 185-km/h relative to the air. There is a wind blowing at 83 km/h to the east relative to ground. What are the plane's speed and direction relative to the ground?

A 13g bullet traveling 221 m/s penetrates a 2 kg block of wood and emerges cleanly at 160 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges.
An ore car of mass 4 000kg rolls downhill on tracks from a mine. At the end of the tracks, 10 m lower in elevation, is a spring with k = 400 000 N/m. How much is spring compressed in stopping the ore car? Ignore friction.
A charge of -3.95 nC and a charge of -5nC are separated by a distance of 30.0 cm. Find the position at which a third charge of +8.00 nC can be placed so that the net electrostatic force on it is zero. How many cm from the -3.95 nC charge and how m..
A horizontal uniform bar of mass 2.7 and length 3.1 is hung horizontally on two vertical strings. String 1 is attached to the end of bar, and string 2 is attached a distance 0.7 from other end. A monkey of mass 1.6 walks from one end of the bar to th..
charge of -2.95 µC is fixed at the center of a compass. Two additional charges are fixed on the circle of the compass, which has a radius of 0.097 m. The charges on the circle are -3.85 µC at the position due north and +5.20 µC at the position due ea..
The two parallel plates in the figure below are 2.0 cm apart and the electric field strength between them is 2.1 104 N/C. An electron is launched at a 45° angle from the positive plate. What is the maximum initial speed v0 the electron can have witho..
You and the friend each drive 47.0 km. You travel at 87.0 km/h; your friend travels at 98 km/h. How long will your friend wait for you at the end of trip.

assume you would enter a vacuum chamber (on Earth), that is, a chamber with no air in it. Inside this chamber, if you dropped a hammer and a feather from the same height at the same time, both would hit the bottom at the same time.
Newton's universal constant of gravitation is G = 6.67 × 10-11 meters cubed (m3) per kilogram per second per second. The Sun's mass is M = 1.9891 x 10^30 kilograms. Earth's orbital period is P = 365.256366 days. Obtain the average radius of Earth's o..
A 245 ball is tied to a string. It is pulled to an angle of 5.20 and released to swing as a pendulum. A student with a stopwatch finds that 10 oscillations take 10.5.
