Cecelia dropped a ball from a height of 2 m. the ball fell in a straight path down to the ground
according to newton’s universal law of gravitation, which would change the path of the ball so it traces out the widest curved path possible?

a)tossing it horizontally at a slower speed
b)tossing it horizontally at a faster speed
c)dropping it from a shorter distance
d)dropping it from a greater distance

A60-kg skier starts at the top of a 10-meter high slope. at the bottom, she is traveling 10 m/s. what is the gpe? gpe =mgh 2,880 j 5,880 j 3,000 j 1633j

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

The energy produced as a result of this flow of electrons from atom to atom is called
