# Acceleration = change of velocity divided by time interval = Δv/Δt. Find the acceleration of a car that can go from rest to 120 km/h in 14 s.

a=2.378 m/s^2

Explanation:

a=Δv/Δt------eq(1)

Δv=Vf-Vi=120 km/h-0 km/h=120 km/h

or Δv=33.3 m/sec

or time=t=14s

putting values in eq(1)

a=33.3/14

a=2.378 m/s^2

Explanation:

A = 2.378M/S^2

A floating ice block is pushed through a displacement d = (23 m) i - (9 m) j along a straight embankment by rushing water, which exerts a force F = (200 N) i - (149 N) j on the block. How much work does the force do on the block during the displacement?

Work is the energy transferred to an object by the application of force along a displacement. The work done by the force on the block during the displacement is 5941 J.

Work is the energy transferred to an object by the application of force along a displacement.

Given Here,

Displacement d = (23 m) i - (9 m) j

Force exerted on the block  F = (200 N) i - (149 N) j

Work formula,

W = F.d

W =  (200 N) i - (149 N) j  . (23 m) i - (9 m) j

Since i.i = j.j = k.k = 1

Hence,

W = 4600 + 1341

W = 5941 J

Hence we can conclude that the work done by the force on the block during the displacement is 5941 J.

Work done, W = 5941 joules

Explanation:

It is given that,

Force exerted on the block,

Displacement,

Let W is the work done by the force do on the block during the displacement. Its formula is given by :

Since, i.i = j.j = k.k = 1

W = 5941 joules

So, the work done by the force do on the block during the displacement is 5941 joules. Hence, this is the required solution.
