The acceleration of an object (in m/s2) is given by the function a ( t ) = 6 sin ( t ) a(t)=6sin(t). the initial velocity of the object is v ( 0 ) = − 2 v(0)=-2 m/s. round your answers to four decimal places. a) find an equation v(t) for the object velocity.

In addition to gravity, what is the other predominant force that affects the motion of a pendulum?

You walk 45 m to the north, then turn 90° to your right and walk another 45 m how far are you from where you originally started? a.45 m b.41 m c.85 m d.64 m

Car batteries are often rated in amp-hours. this rating indicates the quantity of charge that can pass through the battery before the battery's chemical energy must be restored by the car's generator or some other source. the amp-hour unit is convenient for simple calculations. for example, a 60-amp-hour battery can supply a current of 1.0 a for 60 h (or 60 a for 1.0 h) before going dead. find the energy stored in the following. (a) a 58 a-h, 10 v car battery(b) a 1.3 a-h, 1.7 v flashlight battery
