Question

1. A Porsche 911 accelerates from rest to 27 m s-1
due north in 5.8 s. The mass of the car is 1400 kg.
What is the magnitude and direction of the average
net force that acts on the Porsche?​

Answer 1

Answer:

the answer is 6500N

Explanation:

here, we are gonna use the formula f (force) = m (mass) × a (acceleration).

The required formula is v = u+ at

here, u( initial velocity) = 0,as we know that they Porsche has started from rest.

v (final velocity) = 27 m/sec

a ( acceleration) = 27/5.8m/sec = 4.66m/sec

putting the value, in f = m×a,we get

f = m×a

f = 1400 × 4.66

f = 6500N
