Answer:
The force is Inertia
Explanation:
This is an example: He turns the ketchup bottle at an angle toward his plate and smacks the bottom of the bottle until the ketchup comes out. How does inertia affect the ketchup in the bottle? The Inertia keeps the ketchup in the bottle. The Jacksons are driving to the lake when a car in front of theirs slams on its brakes.

Answer:
A baseball (m= 149g) approaches a bat horizontally at a speed of 40.2 m/s (90 mi/h) and is hit straight back at a speed of 45.6m/s (102mi/h). If the ball is in contact with the bat for a time of 1.10ms, what is the average force exerted on the ball by the bat ? Neglect the weight of the ball, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction.
Explanation:
Use the impulse equation (a form of Newton's 2nd Law): FΔt = Δ(mv) where Δ means "change in"
The change in momentum is mBB(vf - vi) = (.150 kg)(-46.9 m/s - 40.5 m/s)
Divide this by the time interval and you get F exerted by the bat in Newtons.
Take care.
Answer:
The heat energy required, Q = 6193.8 J
Explanation:
Given,
The mass of ice cube, m = 18.6 g
The heat of fusion of ice, ΔHₓ = 333 J/g
The heat energy of a substance is equal to the product of the mass and heat of fusion of that substance. It is given by the equation,
<em> Q = m · ΔHₓ joules</em>
Substituting the given values in the above equation
Q = 18.6 g x 333 J/g
= 6193.8 J
Hence, the heat required to melt the ice cube is, Q = 6193.8 J
