The velocity of a particle which moves along the s-axis

is given by s=40-3t^2 where t is in seconds.

Calculate the displacement delta s of the particle during

the interval from t=2 to t=4

A ball is hung from a rope, making a pendulum. When it is pulled 5° to the side, the restoring force is 1.0 N. What will be the magnitude of the restoring force if the ball is pulled 10° to the side?

A space probe is sent to the vicinity of the star Capella, which is 42.2 light-years from the earth. (A light-year is the distance light travels in a year.) The probe travels with a speed of 0.9930c.

ngrid kicks a football with an initial velocity of 12 m/s at an angle of 45° relative to the ground. The horizontal component of the initial velocity to the nearest tenth is m/s.

A 60-watt light bulb has a voltage of 120 volts applied across it and a current of 0.5 amperes flows through the bulb. What is the resistance of the light bulb?

In a laboratory experiment, a diffraction grating produces an interference pattern on a screen. If the number of slits in (including the slit spacing) the same, then The fringes stay the same brightness and get closer together.
