A0.5-kg cart moving on a horizontal frictionless track at 0.6 m/s hits a solid bumber and bounces back with a speed of 0.4 m/s. the impulse on the cart is?

I = 0.5 kg.m/s

Explanation:

given,

mass of the cart = 0.5 Kg

initial speed of cart, u=  0.6 m/s

final speed of cart, v = - 0.4 m/s

impulse of the cart = ?

impulse is equal to the change of the momentum of the cart.

I = m u - m v

I = m (u - v)

I = 0.5 (0.6 - (-0.4))

I = 0.5 x 1

I = 0.5 kg.m/s

impulse on the cart is equal to 0.5 kg.m/s

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
