With good tires and breaks, a car traveling 50 mi/hr on dry pavement can travel 400 ft when the driver reacts to something he se
es and brings the vehicle to a stop. If this is done uniformly, what is the car's acceleration?
1 answer:
Answer:
Explanation:
Given
initial velocity
Distance traveled before stopping
using equation of
where v=final velocity
u=initial Velocity
a=acceleration
s=displacement
v=0 as car stops after travelling
negative sign indicates it is deceleration

Answer:
15 miles
Explanation:
6 miles per hour
2 1/2 hours
6 x 2 = 12
6 x 1/2 = 3
12 + 3 = 15
Answer:
As the object falls it loses potential energy and gains kinetic energy
Explanation:
When the object reaches the ground its final KE will be equal to its original PE
Answer:
D
Explanation: That is the lowest point in a cycle
Answer:
1 m/s² down
Explanation:
"Calculate the acceleration of the elevator, and find the direction of acceleration."
Sum of forces in the +y direction:
∑F = ma
N − mg = ma
0.9 mg − mg = ma
-0.1 mg = ma
a = -0.1 g
a = -1 m/s²
