A vehicle that goes from 5m/s to 45m/s in 8s. what is its acceleration?
GaryK [48]

Answer: 5m/s^2

Explanation:

V= 45m/s

U = 5m/s

t = 8s

a =?

V = u + at

45 = 5 + 8a

8a = 45 — 5

8a = 40

a = 40 / 8

a = 5m/s^2

A block of mass m begins at rest at the top of a ramp at elevation h with whatever pe is associated with that height.
natka813 [3]
 <span>PE = mass * height * g = 87.60 J 

Frictional force = m * g * sin theta * uk = 4.7 kg * 9.81 m/sec^2 * sin 36.87 * 0.3 = 8.299 N 

Work done by friction = force * distance = 41.50 J 

Remaining energy to be converted to KE = 87.60 J - 41.50 J = 41.10 J</span>hope it helps

Can you solve a simple physics problem
mart [117]

Answer:

0.41

Explanation:

A 49 N block has a mass of 5 kg:

49/9.8

A horizontal force of 50 N giving it an acceleration of 6 m/s^2 means that 30 N is taken up by the acceleration

This leaves 20 N to take care for friction. so the coefficient of friction is:

20/49 = 0.41.
