A force is applied to an object of mass 7.23kg such that the object moves according to the equation r 8.45 t .23m) x ­ .23 t .71 t)y . → = ( s 2 m 2 + 5 ˆ + ( 9 s 2 m 2 + 4 s m ˆ (a) What is the magnitude and direction of the object’s velocity at t=5s? (b) What angle is the force being applied to the cart?

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
