Someone please help me! And I will mark you as brainlist!! 1) A ball with a mass of 2.0 kg is thrown upward 1.2m calculate its gravitational potential energy into two significant figures. Gravity = 9.8 N/kg

• 2.4 J
• 1.4 J
• 120 J
• 24 J

2) Translation kinetic energy is defined as the energy of a system due to the motion of the system’s...

• center of mass
• axis of symmetry
• molecules
• rotational movement

3) Shawn and his bike have a combined mass of 45.0 kg. Shawn rides his bike 1.80km in 10.0 min at constant velocity. What is the system’s kinetic energy? Hint: V =d/t

• 203 J
• 450 J
• 18 J
• 81 J
