Problem
Given
m = 8820N Speed = 35m/s Distance = 1100m a = ? ΣF = ?
The parachute on a race car that weighs 8820 N
opens at the end of a quarter-mile run when the car
is traveling 35 m/s. What net retarding force must
be supplied by the parachute to stop the car in a
distance
of 1100 m?
The parachute on a race car that weighs 8820 N
opens at the end of a quarter-mile run when the car
is traveling 35 m/s. What net retarding force must
be supplied by the parachute to stop the car in a
distance
of 1100 m?
Solution
a = velocity/timea = -35m/s ÷ 314.29s a = -0.11m/s²
m = 8820N ÷ 9.8m/s m = 900 kg
Given
m = 8820N
Speed = 35m/s
Distance = 1100m
a = ?
ΣF = ?
ΣF = ma ΣF = 900 kg (-0.11m/s²) ΣF = -99N
T = distance/speedT = 1100m ÷ 35m/s T = 314.29s
What net retarding force must be supplied by the parachute to stop the car in a distance of 1100 m?
ΣF = -99N
