The Acceleration Function of a Body Moving Along a Coordinate $$a ( t ) = - 7 \cos 2 t - 8 \sin 2 t \quad t \geq 0$$

question 21

Short Answer

The acceleration function of a body moving along a coordinate line is
$$a ( t ) = - 7 \cos 2 t - 8 \sin 2 t \quad t \geq 0$$
Find its velocity and position functions at any time $t$ if it is located at the origin and has an initial velocity of $4 \mathrm {~m} / \mathrm { sec }$ .
