Triny is riding a ride at an amusement park with dips and hills. Triny is moving at 16.5 m/s over the top of a hill with a radius of 11.7 m. Use Newton’s 2nd law to determine the magnitude of the net force of Triny’s 85 kg body.

he would use the colour black

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
