Answer:
9ms^2
Explanation:
since ,Force=mass*acceleration
then, acceleration=force/mass
and, Force=90N
Mass=10pound
therefore, acceleration=90/10
=9ms^2
I would help if i could im sorry im sure someone else will answer soon
Answer:
the small car has a larger change in velocity
Explanation:
it has a larger change in velocity because it is small compared to the big truck that hit the car.
Answer:
The tension T in each of the cables, T = 98 N
Explanation:
Given,
The mass of the loudspeaker, m = 20.0 Kg
The suspended distance of the loudspeaker, d = 2.20 m
The length of each cable, l = 2.9 m
The tension experienced by the cable is given by the formula,
T = mg + ma newton
Where,
g - acceleration due to gravity
a-acceleration produced by the stretched cable
Since the stretched cable and loudspeaker is not moving, then the tension force acting on the cable is equal to the force of gravity.
T = mg newton
Substituting the values in the above equation
T = 20
= 20.0 Kg x 9.8 m/s²
= 196 N
This force is equally supported by the two cables, then the tension in each cable is
T = 196 N / 2
= 98 N
Hence, the tension T in each of the cables, T = 98 N
Answer:
The force that the football play kicked the ball with was 6.22n
Explanation:
The reason why it is 6.22N is because when you use the formula, F =MA
and you plug the numbers in, it eaquals 6.22n.
F=0.42*14.8
