Homework Answers
ΔK + ΔP = 0 ;
210 - 380 = - ΔP ;
ΔP = 170 ;
mgh = 170 ;
30 * 9.8 h = 170 ;
h = 0.578231 m <-------ans
Or, 30 *9.8 * h =170
so, h =.578 metre

After coming down a slope, a 63-kg skier is coasting northward on a level, snowy surface at a constant 15 m/s. Her 5.0-kg cat, initially running southward at 3.5 m/s , leaps into her arms, and she catches it. a) Determine the amount of kinetic energy converted to internal energy in the Earth reference frame.(I know this is 790J) b)***What is the velocity, measured in the Earth reference frame, of an inertial reference frame in which the cat's kinetic energy...

A 54 kg pole vaulter intends to pass over a 6.4-meter high bar. She needs to maintain a minimal speed of 0.72 m/s at the top in order to pass the bar. What is the minimum speed at which she should run in order to attain the height? Neglect air resistance, as well as any energy absorbed by the pole Answer in units of m/s and round to one decimal place. Hints: Mechanical energy is conserved during vaulting. KE at...

a) A man jumps off the roof of an office building onto a trampoline 30 m below. His speed is 5 m/s when he umps from the roof and his mass (with all of her gear) is 60 kg. How high will he go when he bounces back up from the trampoline? You can assume his speed at the top of his bounce is zero. b) Describe the changes in mechanical energy that take place during his jump. c) A...

During a pair ice skating, a 60-kg female ice skater leaps into the air and is caught by her 70-kg partner who was stationary. a. Assuming negligible friction on ice what is the velocity of the pair if the horizontal velocity of the female skater right before she was caught in the air was 5 m/s? b. What is the total KE before she was caught? What is the total KE after she was caught? c. Knowing that the skaters...
