Question

A 47.0 g golf ball is driven from the tee with an initial speed of48.0 m/s and rises to a height of24.4 m. (a) Neglect air resistance and determine thekinetic energy of the ball at its highest point.
1 J

(b) What is its speed when it is 6.0 mbelow its highest point?
2 m/s

(b) What is its speed when it is 6.0 mbelow its highest point?
2 m/s
Section 6.5 The Conservation of MechanicalEnergy

Explanation / Answer

e highest point velocity =0m/sec hence kinetic energy=0J speed below 6m v*v=0+2as=0+2gh=2*9.8*6=> v=10.84m/sec
