Can someone help me solve this?

A small mass m slides with negliglble friction down an Incline at an angle of 25.76° with respect to the horizontal. It then drops down to a horizontal surface and bounces elastically back up as shown 5 The picture is to scale. It shows the position of the mass at equal time intervals starting from rest at X. The height of the mass at S is the same as at P. Click here to view the motion of the mass mm . The size of the total force on m at P is less thanat R The mechanical energy of m at V is less than that at S. The size of the total force on m at V Is less than at T. . The speed change between R and U is |equal to between X and R. The speed of m at ssthan that at P The velocity of m at S is less thanthat atP The mass is in contact with the ground for a very brief time. Elastically implies that no energy is lost.

Explanation / Answer

Total force at P is equal to force at R

Mechanical energy of m at V is equal to that at S

Total force on m at V is more than at T

speed change between R and U is equal to the change between X and R

speed at Q is less than that at P

Velocity of mass at S is equal to P
