The significant figures also known as the significant digits or precision of a number written in positional notation are digits that carry meaningful contributions to its measurements
Answer:
Kinetic energy = 35840 Joules
Explanation:
Given the following data;
Mass = 70kg
Velocity = 32m/s
To find the kinetic energy;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;

Where, K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.

Substituting into the equation, we have;



K.E = 35840 Joules.
Therefore, the kinetic energy possessed by the cheetah is 35840 Joules.
X=.5(a)t^2 can be used: 2.5m=.5(g)(1), g=5m/s^2.
