Explanation:
It is given that,
Mass of the ball, m = 0.06 kg
Initial speed of the ball, u = 56 m/s
Final speed of the ball, v = -34.5 m/s (opposite direction)
(a) Let J is the impulse delivered to the ball by the racquet. It is equal to the change in momentum of the object as :


J = -5.43 kg-m/s
(b) The work done by the racquet on thee ball is equal to the change in kinetic energy as :


W = -58.372 Joules
Could be c because it matches the question
Answer:
Particles can be classified as hadrons – baryons and mesons – and leptons, each with its anti-particle, and they should know that interactions between these particles can be described in terms of transfer of other particles known as vector bosons.
Explanation:
Your Welcome, if you could give me Brainlist I would appreciate it!
Explanation:
KE = KE
½ mv² = ½ mv²
½ (1.88 g) v² = ½ (230.5 g) (58.5 m/s)²
v = 648 m/s
I’m not really sure but I think it’s D type 1 lever
