Respuesta :
The acceleration of the car is 1.4 m/s².
What is acceleration?
This can be defined as the rate of change of velocity.
To calculate the acceleration of the car, we use the formula below.
Formula:
- Tcos∅ = ma+mgμ............. Equation 1
Where:
- T = Tension in the cable
- m = mass of the car
- a = acceleration of the car
- g = acceleration due to gravity
- ∅ = angle of the cable to the horizontal
- μ = coefficient of friction.
Make a the subject of the equation.
- a = (Tcos∅-mgμ)/m............ Equation 2
From the question,
Given:
- T = 6510 N
- m = 1550 kg
- ∅ = 37°
- g = 9.8 m/s²
- μ = 0.198
Substitute these values into equation 2
- a = [(6510cos37)-(1550×9.8×0.198)]/1550
- a = (5199.12-3007.62)/1550
- a = 2191.5/1550
- a = 1.4 m/s².
Hence, the acceleration of the car is 1.4 m/s².
