The deceleration of the car is 3 m/s².
<u>Explanation:</u>
So the initial velocity of the car is given as 12 m/s. As the car is said to slow down and then it stops after 4 seconds, so the final velocity is zero.
We know that the acceleration acting on any object to stop the motion of that object is termed as deceleration or negative acceleration.
This is because, acceleration is the ratio of change in velocity to time taken for that change in velocity.
So.,
So the deceleration of the car is 3 m/s².
Answer:
John Felix Anthony Cena is an American professional wrestler, actor, and television presenter. He is currently signed to WWE. Born and raised in West Newbury, Massachusetts, Cena moved to California in 1998 to pursue a career as a bodybuilder.
Explanation:
Answer:
A. 1.96 m/s.
B. 0.35 m.
C. 0.15 m.
Explanation:
A.
Velocity of a wave,v = f * lambda
Where,
f = frequency of the wave
Lambda = wavelength
Given:
T = 2.8 s
f = 1/T
= 1/2.8
= 0.36 hz
Lambda = 5.50 m
V = 5.5 * 0.36
= 1.96 m/s.
B.
Amplitude, a = distance/2
= 0.7/2
= 0.35 m.
C.
Amplitude, a = 0.3/2
= 0.15 m.
Answer:
C
Explanation:
force equals mass time acceleration
It would fall at about/ around 96 mph
