A car of mass 1.5x 105 kg is initially travelling at a speed of 25 m/s. The driver then accelerates to a speed of 40m/s over a distance of 0.20 km. Calculate the work done on the car. 3.8x105 J 7.3x107 7.3x105J 7.3x103 Question 10 (1 point) A 86g golf ball on a tee is struck by a golf club. The golf ball reaches a maximum height where its gravitational potential energy has increased by 255 J from the tee. Determine the ball's maximum height above the tee. 303m 34m 0.3m 30m Section 3: Communication Question 11 (1 point) Which of the following statements correctly describes the relationship between an object's gravitational potential energy and its height above the ground? proportional to the square of the object's height above the ground directly proportional to the object's height above the ground inversely proportional to the object's height above the ground proportional to the square root of the object's height above the ground Question 12 (1 point)
