you hold a 1 kg basketball 1.5 m above the ground in order to calculate the coefficient of restitution. In this instant, what is the gravitational potential energy of the basketball?
a. 23 J
b. 37 J
c. 72 J
d. 18 J
Using the information from the previous question, if you were to release the basketball, what would be its velocity the moment before it hits the ground?
a. 78 m/s
b. 43 m/s
c. 42 m/s
d. 9.81 m/s
Homework Answers
Solution) given
M= 1kg
h = 1.5m
Gravitational potential energy PE = Mgh =1×9.8×1.5=14.7J
PE =14.7 J
NOTE :Kindly check options for above problem
Velocity v=(2gh)^(1/2)=(2×9.8×1.5)^(1/2)= 5.42 m/s
NOTE: Kindly check options
