the net external force on a golf cart is 390 n north. if the cart has a total mass of 220 kg. what is the magnitude and direction of its acceleration
a = F/m = 390N[90o]/220 = 1.77m/s^2[90o]
=1.77m/s^2, North.
To calculate the magnitude and direction of the golf cart's acceleration, we can use Newton's second law of motion: F(net) = m * a, where F(net) is the net external force, m is the mass, and a is the acceleration.
Given:
F(net) = 390 N north
m = 220 kg
To find the magnitude of acceleration:
We can rearrange the formula to solve for acceleration (a): a = F(net) / m
Substituting the given values:
a = 390 N / 220 kg
Calculating the magnitude of acceleration:
a ≈ 1.77 m/s² (rounded to two decimal places)
To find the direction of acceleration:
Since the net force is stated to be in the north direction, the acceleration will also be in the same direction. So, the direction of the acceleration is north.
Therefore, the magnitude of acceleration is approximately 1.77 m/s², and its direction is north.
