1. A m kg block is released from resttouching a spring with spring constant of 237J/m2 and an initial compression of 10.4 cm as shownin the figure. The angle is 44 degrees above the horizontal. If themaximum distance travelled by the block up the inclined surface iss = 20.5 cm, what is the block of the mass m (inkg)? You may treat this as an isolated system. 2. A player is able to accelerate a 0.9 kg ball from rest to aspeed of v m/s. If the work done on the ball bythis player is 227 J, what is the speed v (inm/s) of the ball? You may assume that the ball travels perfectlyhorizontally (i.e., parallel to the ground) duringits acceleration.
