The tension cable is in relation to the amount of pressure placed on the upper plate
Answer:
The answer to your question is: a = 2 m/s²
Explanation:
I' ll solve it in this way, tell me if I'm right. Because we need to consider that in the moon there is no gravity.
Data
F = 50 N
a = 4.0 m/s²
Moon
F = 25 N
a = ?
Formula
F = m x a
First, calculate the mass
m = F / a
m = 50 / 4
m = 12.5 kg
Now, calculate the acceleration
a = F / m
a = 25 / 12.5
a = 2 m/s²
Total distance between Sally's house and mall = 10 kilometers
Distance covered during half way drive = Kilometers
Now, she goes back to her home.
Distance covered going back home = Kilometers
Now, she drives from home to mall.
Distance covered from Sally's home to mall = 10 kilometers
Hence, the total distance Sally traveled = 5 + 5 + 10
Total distance Sally traveled = 20 kilometers
Hence, the answer is 20 kilometers
Answer:
F = 11046 N
Explanation:
given,
mass of the baseball (m)= 145 g = 0.145 Kg
horizontal speed(u) = -36 m/s
ball hit is straight back(v) = 47.8 m/s
time of contact = ?
using formula of impulse
Impulse = change in momentum
I = m v - m u
I = 0.145 x (47.8 - (-36))
I = 0.145 x (83.8)
I = 12.151 kg.m/s
we also know
I = F x t
now,
F x t = 12.151 kg.m/s
F x 1.1 ms = 12.151
F = 11046 N
