In a football game a kicker attempts a field goal. The ball remains in contact with the kicker's foot for 0.0682 s, during which time it experiences an acceleration of 295 m/s2. The ball is launched at an angle of 52.8° above the ground. Determine the
(a) horizontal and
(b) vertical components of the launch velocity.
A moving body undergoes uniform acceleration while travelling in a straight line between points X, Y and Z. The distances XY and YZ are both 40m. The time to travel from X to Y is 12s and from Y to Z is 6s.
