Answer:
a. 12,600 N
b. 1290 kg
Explanation:
a. Impulse = change in momentum
F Δt = m Δv
F (0.192 s) = (59 kg) (0 m/s − 41 m/s)
F = -12,600 N
b. F = mg
12,600 N = m (9.8 m/s²)
m = 1290 kg (or 2,830 lbs)
D. A bimetallic strip bends so that the steel is on the outside curve.
Assume theres no air reaistance. (or else the ball will oppose the motion of the ball, hence decrease the velocity increase)
see if there are any problems!
Answer:
An outside force
Explanation:
Newton's law an object in motion stays in motion an object at rest stays at rest unless acted on by an outside force.
