What was the magnitude of the average force applied by the ball on the glove?

question #2

How much tension must a rope withstand if it is used to accelerate a 1180kg car horizontally along a frictionless surface at 1.20m/s^2 ?

a ={v(f)^2 – v(i)^2}/2•s = - v(i)^2}/2•s = 30^2/2•0.14=3.21•10^3 m/s^2

F = m•a =0.14•3.21•10^3 =450 N

#2

T=F= m•a = 1180•1.2 =1416 N
