After landing on a distant exoplanet as a member of the Space Force Spec Ops Team one of your first tasks is to measure the gravity on the surface of the planet. Your weight feels heavier than on Earth, but that might just be the 80 kg spacesuit you are wearing. You pull out a 45.93 gram golf ball and drop it from eye level while recording the time it takes to hit the ground. You record 0.44 seconds for it to hit the ground. You have previously measured your eye level height to be 146 cm in preparation of this task. Using this information calculate the gravity on this new planet.

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?

Aspring that is stretched 2.6 cm stores a potential energy of 0.053 j. what is the spring constant of this spring?

The following statements are about the electroscope. select all that are true. if an electroscope were given a positive charge beforehand, the leaves would move closer together if a positively charged object were brought near. when a properly prepared electroscope is used to determine the type of charge on an object, the total charge on the electroscope changes when the charged object is brought near (but not touching) the electroscope. depending on how the electroscope is prepared beforehand, the leaves can either move together or move apart when negative charge is brought near. an electroscope must first be given a known type of charge before it can be used to identify the types of charges on objects brought near it. when properly prepared, the leaves on an electroscope will always move further apart when negative charge is brought near. the leaves of an electroscope will move apart if it is given either a positive or a negative charge.
