Answer:
mass
Explanation:
As this is directly related to inertia. Inertia is the property of unit which resists the change of state of rest or motion
Answer:
195
Explanation:
he can only apply as much force as his body mass so it would be 195
The answer to this is that it is FALSE!
Answer:
299.51 m/s
Explanation:
m = mass of the bullet = 45 g = 0.045 kg
M = mass of the block = 1.55 kg
v = muzzle speed of the bullet
V = speed of bullet-block combination after the collision
μ = Coefficient of friction between the block and the surface = 0.28
d = distance traveled by the block = 13 m
V' = final speed of the bullet-block combination = 0 m/s
acceleration of the bullet-block combination due to frictional force is given as
a = - μg
using the kinematics equation
V'² = V² + 2 a d
0² = V² + 2 (- μg) d
0 = V² - 2 (μg) d
0 = V² - 2 (0.28) (9.8) (13)
V = 8.45 m/s
Using conservation of momentum for collision between bullet and block
mv = (M + m) V
(0.045) v = (1.55 + 0.045) (8.45)
v = 299.51 m/s
