kinetic energy is increasing
potential energy is increasing
potential energy is decreasing
kinetic energy remains constant
Correct answer is B
The Kinetic Energy of a body is energy possessed by a body as a result of its motion. Hence, while in motion the kinetic energy of a body changes into potential energy as it rebounds from the floor
0.60ms-1
0.67ms-1
2.00ms-1
3.33ms-1
Correct answer is B
\(M_1V_1 - (M_2V_2) = V(M_1 + M_2)\)
2 x 3 - 1 x 4 = V(2 + 1)
V = \(\frac{2}{3}\)
= 0.67ms-1

halved
four times as great
one-fourth as much
