The change in kinetic energy (in joules) as a horse accelerates from canter to gallop is found using the expression 1/2 times 350 times (12 2 Minus 6 2

Step-by-step explanation:

Given that:

the expression for the change in kinetic energy =

Recall that

Kinetic energy K.E =

where,

m = mass of the horse

v = velocity of the horse

The change in kinetic energy between  two instant times can be expressed by the relation

where;

m = 350

= 122

= 62

angle addition postulate

2x=56
