A cannonball is launched at an angle and travels above the flat ground. At what time point does the projectile reach its maximum height?

• One-fifth of the total time in the air
• One-fourth of the total time in the air
• One-half of the total time in the air
• Three-fifths of the total time in the air

Object A, when acted upon by a force F, accelerates at a rate of 4.0 m/s/s. This same force accelerates Object B at a rate of 8.0 m/s/s. Compared to the mass of Object A, the mass of Object B is:

• Four times as great
• Twice as great
• The same
• One-half as great

A mass is attached to a spring and allowed to oscillate vertically. Which of the following would NOT change the period of the oscillation?

• Double the mass and double the spring constant
• Double the amplitude of vibration and double the mass
• Double the gravitational field strength and double the mass
