To find the height of the ball 1.4 seconds after it is thrown, substitute $t = 1.4$ into the given function $h(t) = -16t^2 + 33.1t + 124.26$. Calculation: $h(1.4) = -16(1.4)^2 + 33.1(1.4) + 124.26 = 139.24$.

Solve the Problem h(t)=−16t2+33.1t+124.26h ( t ) = - 16 t ^ { 2 } + 33.1 t + 124.26h(t)=−16t2+33.1t+124.26

Solve the Problem $h ( t ) = - 16 t ^ { 2 } + 33.1 t + 124.26$
