Answer: Car collide with man
Explanation:
Given
Speed of car is
Distance of the man from the car is
Reaction time
Rate of deceleration
Distance traveled in the reaction time
Net effective distance to cover
Distance required to stop the car
Require distance is more than that of net effective distance. Hence, car collides with the man.

Answer:
41.3 m/s^2 option (e)
Explanation:
force, F = 6.81 N
mass, m = 165 g = 0.165 kg
Let a be the acceleration of the puck.
Use newtons' second law
Force = mass x acceleration
6.81 = 0.165 x a
a = 41.27 m/s^2
a = 41.3 m/s^2
Thus, the acceleration of the puck is 41.3 m/s^2.
Answer:
(a). The average current flows through the dryer is 12.5 A
(b). The resistance of the dryer is 9.6 Ω
Explanation:
Given that,
Voltage = 120 V
Power = 1500 W
(a). We need to calculate the average current flows through the dryer
Using formula of current
Where, P = power
V = voltage
Put the value into the formula
(b). We need to calculate the resistance of the dryer
Using Ohm's law
Where, I = current
Put the value into the formula
Hence, (a). The average current flows through the dryer is 12.5 A
(b). The resistance of the dryer is 9.6 Ω
The answer is A.68 degrees
