A 1500 kg car starts from rest,
and rolls down a frictionless 5.09°
slope that is 17.5 m long. How
much time does it take to reach
the bottom?
(Unit = s)

Respuesta :

The time taken for the heavy car to reach the bottom of the frictionless slope is 0.56 s.

Height of the slope

The height of the incline is calculated as follows;

sin θ = h/L

h = L sinθ

where;

  • L is length of slope
  • h is height of the slope

h = 17.5 x sin(5.09)

h = 1.55 m

Time of motion of the car

t = √(2h/g)

where;

  • t is time of motion
  • g is acceleration due to gravity

t = √(2 x 1.55 /9.8)

t = 0.56 s
