Kinetic energy depends on the mass and the speed of a moving object.
If the speeds are equal, then the rick with more mass has more kinetic energy.
Red shirt appears red because:
a. The shirt reflects red light
Answer:
The value of F= - 830 N
Since the force is negative, it implies direction of the force applied was due south.
Explanation:
Given data:
Mass = 1000-kg
Distance, d = 240 m
Initial velocity, v1 = 20.0 m/s
Final velocity, v2 = 0 (since the car came to rest after brake was applied)
v2²= v1² + 2ad (using one of the equation of motion)
0= 20² + (2 x a x 240)
0= 400 + 480 a
a = - 400/480
a = - 0.83 m/s²
Then, imputing the value of a into
F = ma
F = 1000 kg x ( - 0.83 m/s²)
F= - 830 N
The car was driving toward the north, and since the force is negative, it implies direction of the force applied was due south.
Answer: 9m
Explanation:
Our given:
Acceleration- 5m/s^2
Time- 3.6 seconds
Use the equation d = 1/2 • a • t^2
d = 1/2 • 5m/s^2 • 3.6 secs
d = 2.5m/s^2 • 3.6 secs
d = 9m
I hope this is correct
