The work done​  to the horizontal direction of displacements the body is 3200 joule.

A force must be applied and there must be movement in the force's direction for a work to be completed scientifically.

With that said, we may state that Work is the product of the force's component acting in the displacement's direction and its magnitude.

Applied force = 400 N

Displacement in the direction of force = 8 m

Hence, work done = 400 ×  Joule = 3200 joule.

When the rock is thrown upwards with a velocity of 19m/s then velocity after 1s is 15.28m/s, the time the rock hit the surface is 10.21s and the velocity with which it hits is 18.98m/s

Given the velocity of rock is (v) = 19m/s

The height of rock above the ground = h = 19t − 1.86t^2.

The time taken to reach that height is = t

(a) We know that the change in velocity is seen as: v(t) = d(H)/dt

V(t) = d(19t − 1.86t^2)/dt = 19 - 2 x t x 1.86 = 19

At t = 1s then, V(1) = 19 - 2 x 1 x 1.86 = 15.28m/s

(b) When t = a then,

V(a) = 19 - 3.72a

(c) The rock hits the surface when the height = 0m such that;

H(t) = 0

19t - 1.86t^2 = 0

t(19 - 1.86t) = 0

t = 19/1.86 = 10.21s

(d) The  rock hit the surface with the velocity obtained at height = 0m. Then, V(10.21) = 19 - 3.72(10.21) = 19 - 37.98 = -18.98m/s

Impulse is the process that changes the translational momentum of a system is a true statement.

According to the impulse-momentum theorem, an object's applied impulse is equal to the change in its momentum. It demonstrates how an object's change in momentum is influenced by both the force's intensity and duration. Only the size of the force and the time interval may typically be changed when the change in momentum is constant. For instance, a significant force applied for a brief period of time can have an impact on an object's change in momentum. By lengthening the period at a weaker force, the same change in momentum can be achieved. Momentum can be found in every moving object. Because momentum is mass in motion, this is the case. Our method for calculating an object's momentum is fairly simple. The formula for momentum is p=mv, where p stands for momentum, m for mass in kilogrames, and v for velocity in meter per second. Momentum is the product of an object's mass and velocity. Both mass and velocity are proportional to momentum, thus a change in one will result in an equal change in the other. Therefore, if you add to the mass of an item, you likewise add to its momentum.
