Answer:
7.4m/s
Explanation:
a=(v-u)/t
v= final velocity
u= initial velocity
note: when a body starts from rest,initial velocity,u=o
a= 18.5-0/2.5
a=7.4m/s
Answer:
M= mv= 10kg x 37 m/s= 370 Kg x m/s
I’m going to assume initial velocity is 0.
Use Newton’s second law:
F = m•a
F/m = a
14.0/32.5kg= 28/65 m/s^2
Use constant SUVAT acceleration formulae:
S- displacement - what we need to find out
U - initial velocity - 0
V
A - 28/65 m/s^2
T - 10 seconds
S = ut + 1/2at^2
Since u = 0
S = 1/2at^2
1/2• 28/65 • 10^2 = 21.5metres~
Answer is 21.5 metres
