Question

A 73.4 kg basketball player

accelerates herself upward at

2.25 m/s. How much upward

force does she exert?

(Hint 1: Don't forget her weight!)

(Hint 2: Her force is not the same thing as

the Total Force.)

(Unit = N)

Answer 1

884.47 N

Explanation: Given that

g = 9.8m/s^2

a = 2.25m/s^2

m 73.4kg

F - mg = ma

F = mg + ma

= m(g + a)

= 73.4 ( 9.8 + 2.25)

= 884.47 N
