Due to a pulling force P, a 3-kg ball was given an initial speed of 7 m/s with constant acceleration to move from the bottom of an inclined plane, with an angle of elevation of 40, to the top of the said plane. Determine the acceleration needed for the ball to reach and stop at the top of the inclined plane in just 4 seconds. Determine also the total distance travelled by the ball during its ascent. Considering k = 0.2, determine the value of P
