Explanation:

a =  \frac{change \: in \: velocity}{change \: in \: time}

a =  \frac{v - u}{t}

v = 7 {ms}^{ - 1}

u = 15 {ms}^{ - 1}

t = 3 \: seconds

a =  \frac{7 - 15}{3}

a =   \frac{ - 8}{3}

a =  - 2.67 \:  {ms}^{ - 2}

Calculate the centripetal force acting on a 925 kg car as it rounds an unbanked curve with a radius of 75 m at a speed of 22 m/s
igomit [66]
Since f=m(v^2/r),or fnet is equal to ma.

force = unknown
velocity=22m/s
radius=75m


f=m(v^2/r)
f=925(22^2/75)
f=5969.333N
