Ok, you need to stop posting all these questions and, instead, focus on one at a time. Once you solve your lion question, then you should be able to tackle this one.

Is that 1.47 x 102 Newtons?

F = ma(gravity)

### tim_mannire

yes that is correct. is that the formula i am to use?

### Vikingjl11

yes, F(force)=M(mass) x a(acceleration)- In this case "a" equals accel. due to gravity.

Ok. So what is the force and the mass in this question?

A newton is a quantity of Force, you are attempting to find mass, acceleration due to gravity is a constant
