2. Bob throws a 500 g rock at 25 m/s, moving his hand through 1.0 m as he accelerates it from rest. If Bob is standing on ice, he will slide backwards. Bob's mass is 75 kg. Solve this question in two ways:
a) Write Newton's 2nd Law for Bob and the rock. Use kinematics to get the rock's acceleration.
A girl of m1=60 kg springs from a trampoline with an initial upward velocity of Vi=8.0 m/s. what is the speed of the girl immediately before she grabs the box
A block weighing 60.0 N rests on a plane inclined at 25.0° to the horizontal. A force F is applied to the object at 44.0° to the horizontal, pushing it upward on the plane. The coefficients of static and kinetic friction between the block and the pla..
A 275 ball is tied to a string. It is pulled to an angle of 4 and released to swing as a pendulum. A student with a stopwatch finds that 17 oscillations take 20.
